Full syllabus: every lesson in the Ruby roadmap
19 stages and 102 lessons, in the order the roadmap suggests. Every lesson is free to read and open from the start.
Stage 1: Introduction
Introduction
Ruby is a dynamic, open-source programming language known for its simplicity and productivity. It emphasizes human readability, using a syntax that is easy to learn and write. Ruby is object-oriented, meaning everything is treated as an object, and it supports multiple programming paradigms, including procedural,…
Stage 2: Setting things Up
Setting things Up
Installing Ruby involves setting up the Ruby interpreter and related tools on your system so you can run Ruby programs. This typically includes downloading a Ruby distribution, configuring your environment, and verifying the installation to ensure everything is working correctly. Different operating systems (like…
Package Managers
Package managers simplify the process of installing and managing software, including Ruby, on your system. Instead of manually downloading and configuring Ruby, you can use a package manager specific to your operating system. For example, on macOS, you might use Homebrew, while on Debian/Ubuntu Linux, you'd use…
Installers
Installers are software packages designed to simplify the process of setting up Ruby on your computer. They typically handle downloading the necessary files, configuring your system environment, and ensuring that Ruby and its related tools are ready to use. Using an installer avoids the complexities of manual…
Managers
Ruby version managers are tools that allow you to install and manage multiple versions of Ruby on the same system. This is useful because different projects may require different Ruby versions, and using a version manager prevents conflicts and simplifies switching between them. They typically work by modifying…
Stage 3: Constants & Variables
Constants & Variables
In Ruby, variables are named storage locations that hold data, and their values can be changed during the program's execution. Constants, on the other hand, are also named storage locations, but their values are intended to remain fixed throughout the program's runtime. While Ruby technically allows you to reassign…
Stage 4: puts, print, p
puts, print, p
puts, print, and p are methods in Ruby used to display output to the console. puts prints the given arguments followed by a newline character, print prints the arguments as they are without adding a newline, and p prints a human-readable representation of the given object, which is useful for debugging.
Stage 5: Comments
Comments
Comments are notes in your code that the Ruby interpreter ignores. They're used to explain what the code does, making it easier for you and others to understand. You can create a single-line comment by starting a line with a . For multi-line comments, you can use =begin and =end blocks; anything between these…
Stage 6: Naming conventions
Naming conventions
Naming conventions are a set of rules or guidelines for choosing names for variables, methods, classes, and other entities in a programming language. These conventions promote code readability, maintainability, and consistency across projects. Following a standard naming style helps developers understand the…
Stage 7: Data Types
Data Types
Naming conventions are a set of rules or guidelines for choosing names for variables, methods, classes, and other entities in a programming language. These conventions promote code readability, maintainability, and consistency across a project. Following a standard naming scheme helps developers understand the…
Integers
Integers are whole numbers, meaning they don't have any fractional or decimal parts. They can be positive, negative, or zero. In programming, integers are used to represent countable quantities, indices, and other discrete values.
Floats
Floats represent real numbers with fractional parts in Ruby. They are used to store numerical values that require more precision than integers can provide. Floats are typically represented using a decimal point or in scientific notation.
Strings
Strings are sequences of characters used to represent text. They are a fundamental data type for storing and manipulating textual information. Strings can contain letters, numbers, symbols, and spaces, and are typically enclosed within single or double quotes.
Booleans
Booleans represent truth values: either true or false. They are fundamental for decision-making in Ruby code, allowing programs to execute different blocks of code based on whether a condition is true or false. Boolean values are the result of logical operations and comparisons.
Arrays
Arrays in Ruby are ordered collections of items. They can hold any type of data, including numbers, strings, symbols, or even other arrays. You create an array using square brackets [], with elements separated by commas. Arrays are dynamic, meaning their size can change as you add or remove elements. You can access…
Hashes
Hashes are collections of key-value pairs. Think of them like dictionaries, where each word (the key) has a definition (the value). Keys are unique within a hash, and they are used to quickly access their corresponding values. Hashes can store any type of data as keys and values, making them a versatile way to…
Symbols
Symbols are lightweight, immutable strings often used as identifiers or names within a Ruby program. Unlike regular strings, symbols are guaranteed to be unique; Ruby only creates one copy of a symbol, regardless of how many times it's referenced. This makes them efficient for tasks like hash keys or representing…
nil
nil represents the absence of a value or a non-existent object. It's a special object in Ruby that signifies emptiness or the lack of a meaningful result. Think of it as a placeholder indicating that a variable or expression doesn't currently hold a valid value.
Stage 8: Type Casting
Type Casting
Type casting, also known as type conversion, is the process of changing a value from one data type to another. This is often necessary when you need to perform operations that require specific data types or when you want to represent data in a different format. For example, you might need to convert a string…
Stage 9: Operators
Operators
Operators are special symbols in Ruby that perform operations on one or more operands (values or variables). These operations can include arithmetic calculations (like addition and subtraction), comparisons (like checking if two values are equal), logical evaluations (like determining if a condition is true or…
Arithmetic
Arithmetic operators are symbols that perform mathematical calculations on numerical values. These operators allow you to perform addition, subtraction, multiplication, division, and other common arithmetic operations. They take one or more operands (the values being operated on) and produce a result based on the…
Comparison
Comparison operators are symbols used to compare two values. These operators evaluate to either true or false based on the relationship between the values being compared. Common comparison operators include equal to (==), not equal to (!=), greater than (), less than (<), greater than or equal to (=), and less than…
Logical
Logical operators in Ruby let you combine or modify boolean expressions (true or false). The main ones are && (and), || (or), and ! (not). && returns true only if both operands are true. || returns true if at least one operand is true. ! reverses the boolean value of its operand, turning true into false and vice…
Assignment
Assignment operators in Ruby are used to assign values to variables. The most basic assignment operator is the equals sign (=), which assigns the value on the right-hand side to the variable on the left-hand side. Ruby also provides compound assignment operators that combine assignment with arithmetic or bitwise…
Ranges
Ranges in Ruby are used to create a sequence of values. They are defined using two endpoints, which can be numbers, characters, or any objects that can be compared using the <= operator. Ranges can be inclusive (including the last value) or exclusive (excluding the last value), denoted by .. and ... respectively.…
Stage 10: Conditional Statements
Conditional Statements
Conditional statements allow you to execute different blocks of code based on whether a certain condition is true or false. They provide a way to control the flow of your program, enabling it to make decisions and respond differently to various inputs or situations. Common conditional statements include if, elsif,…
unless
unless is a conditional statement in Ruby that executes a block of code only if a specified condition is false. It's essentially the opposite of if. If the condition provided to unless evaluates to false, the code block is executed; otherwise, the code block is skipped. It provides a more readable way to express…
case
A case statement in Ruby provides a way to execute different blocks of code based on the value of a variable or expression. It's an alternative to using multiple if/elsif/else statements, especially when you need to check for several different possible values. The case statement compares a given value against…
if, elsif, else
Conditional statements allow you to execute different blocks of code based on whether a certain condition is true or false. The if statement executes a block of code if a condition is true. The elsif statement (optional) allows you to check additional conditions if the initial if condition is false. The else…
Stage 11: Loops & Enumerations
Loops & Enumerations
Loops in Ruby allow you to execute a block of code repeatedly. Enumerations, on the other hand, are methods that iterate over collections like arrays and hashes, applying a block of code to each element. Both loops and enumerations provide ways to process data and perform actions multiple times, but enumerations…
while
A while loop in Ruby repeatedly executes a block of code as long as a specified condition is true. It checks the condition before each iteration, and if the condition is false from the start, the code block is never executed. This makes it suitable for situations where you want to execute code an unknown number of…
until
The until loop in Ruby executes a block of code as long as a specified condition is false. It repeatedly runs the code within the loop until the condition becomes true. Think of it as the opposite of a while loop; where while loops continue as long as the condition is true, until loops continue as long as the…
do/while
do/while loops are a type of control flow statement that executes a block of code at least once, and then repeatedly executes the block as long as a specified condition is true. The condition is checked after the code block is executed, ensuring the block runs at least one time regardless of the initial state of…
for
The for loop in Ruby provides a way to iterate over a sequence of values, such as elements in an array or a range. It executes a block of code for each item in the sequence. While functional, the for loop is not as commonly used in Ruby as other iteration methods like each, map, or select, which are often…
each
each is a fundamental method in Ruby used to iterate over elements within a collection, such as an array or a hash. It applies a given block of code to each element in the collection, allowing you to perform operations on every item. The each method does not modify the original collection; it simply iterates…
times
The times method in Ruby is a simple way to execute a block of code a specified number of times. It's called on an integer, and the block is executed that many times, with an optional block variable representing the current iteration number (starting from zero). It provides a concise way to repeat actions without…
break
The break statement in Ruby is a control flow tool used to exit a loop prematurely. When break is encountered within a loop (like for, while, until, or each), the loop's execution is immediately terminated, and the program continues with the next statement after the loop. It's useful for stopping a loop when a…
next
The next keyword in Ruby provides a way to skip the current iteration of a loop and proceed directly to the next iteration. When next is encountered within a loop (like for, while, until, or iterators like each), the remaining code in the current loop cycle is bypassed, and the loop immediately begins its next…
redo
redo is a control flow statement in Ruby used within loops (like for, while, until) and iterators (like each, map). When redo is encountered, it restarts the current iteration of the loop or iterator from the beginning, without evaluating any remaining code in that iteration. It essentially repeats the current step.
Stage 12: Enumerable
Enumerable
Conditional statements allow you to execute different blocks of code based on whether a certain condition is true or false. They provide a way to control the flow of your program, enabling it to make decisions and respond differently to various inputs or situations. Common conditional statements include if, elsif,…
Querying
Enumerable querying methods in Ruby allow you to gather information about a collection without necessarily extracting or transforming its elements. These methods check for the presence of elements that meet certain conditions, determine the size or characteristics of the collection, or verify if all or any elements…
Fetching
Enumerable comes with some methods that allow you to retrieve entries from the Enumerable, without modifying it. This includes methods to get leading and trailing elements, extract minimum and maximum value elements, as well as conduct groups, slices, and partitions.
Searching & Filtering
Enumerable comes with some methods that allow you to select specific elements from a collection based on certain criteria. This allows you to extract subsets of data that meet your desired conditions, making it easier to work with large datasets or focus on relevant information. Common operations include finding…
Sorting
The Enumerable module in Ruby provides several methods for sorting collections. These methods allow you to arrange elements in ascending or descending order based on their natural ordering or a custom comparison logic. The most common sorting methods include sort, which returns a new sorted array, and sortby, which…
Iterating
The Enumerable module in Ruby provides a collection of methods that allow you to traverse and process elements within a collection (like an array or hash). These iterating methods, such as each, map, select, and reject, simplify the process of performing actions on each item in the collection, transforming the…
Stage 13: Handling exceptions
Handling exceptions
Exception handling is a mechanism to deal with errors that occur during the execution of a program. It involves identifying potential error-prone sections of code, anticipating possible exceptions, and implementing specific blocks of code to gracefully handle these exceptions, preventing the program from crashing…
begin, rescue, ensure
Exception handling is a mechanism to deal with errors that occur during the execution of a program. In Ruby, the begin, rescue, and ensure keywords provide a structured way to handle these exceptions. The begin block encloses the code that might raise an exception. If an exception occurs, the rescue block catches…
Stage 14: Interactive Ruby (irb)
Interactive Ruby (irb)
Interactive Ruby (irb) is a command-line tool that allows you to execute Ruby code interactively. It provides a read-eval-print loop (REPL) environment where you can type in Ruby expressions, and irb will immediately evaluate and display the result. This makes it a valuable tool for experimenting with code, testing…
Stage 15: Date & Time
Date & Time
Date and Time represent specific points in time. They allow you to work with dates (year, month, day) and times (hour, minute, second) and perform operations like calculating durations, formatting dates for display, and comparing different points in time. They are essential for handling events, scheduling tasks,…
Stage 16: Regex
Regex
Regular expressions (regex) are patterns used to match character combinations in strings. In Ruby, you can use regex to search, replace, or validate text within strings. They are defined using forward slashes (/pattern/) or the %r{pattern} syntax and provide a powerful way to manipulate and analyze text data based…
Stage 17: File I/O
File I/O
File I/O involves reading data from and writing data to files. It allows your Ruby programs to interact with files on your computer's file system. You can open files, read their contents line by line or in chunks, write new data to them, or append data to existing files. This interaction is essential for tasks like…
Defining methods
Methods, also known as functions in other programming languages, are reusable blocks of code designed to perform a specific task. Defining a method involves specifying its name, the parameters it accepts (if any), and the sequence of instructions it executes. This allows you to organize your code into logical…
Method Parameters
Method parameters, also called arguments, are the values you pass into a method when you call it. There are several types: required parameters, which must be provided; optional parameters, which have default values if not provided; and variable-length arguments (using args), which allow you to pass in an arbitrary…
Scope
Scope refers to the visibility and accessibility of variables within different parts of a program. It determines where a variable can be accessed and used. Understanding scope is crucial for avoiding naming conflicts and ensuring that data is accessed and modified correctly within different parts of your Ruby code.
Chaining Methods
Chaining methods in Ruby lets you call multiple methods on an object in a single line of code. This works because most methods in Ruby return an object (often self, the object the method was called on). By returning an object, the next method in the chain can be immediately called on the result of the previous…
RubyGems
RubyGems is a package management system for the Ruby programming language. It provides a standard format for distributing Ruby programs and libraries (called "gems"), a tool for easily installing gems, and a central repository (RubyGems.org) for finding and sharing them. It simplifies the process of managing…

It tracks and installs the specific gem versions required by a project, creating a consistent environment across different machines and deployments. This…
Stage 18: Metaprogramming
Metaprogramming
Metaprogramming is essentially writing code that manipulates other code. It allows you to define methods, classes, or even modify existing ones at runtime. This means your program can dynamically adapt and change its behavior based on conditions or data it encounters while running, rather than being fixed at…
send
send in Ruby is a method that allows you to call other methods on an object dynamically by their name, which is passed as a symbol or string. It essentially bypasses the usual method call syntax, enabling you to invoke methods at runtime based on conditions or data. This provides a powerful way to write flexible…
define_method
definemethod is a method used to dynamically create new methods within a class or module. Instead of explicitly writing out the method definition with the def keyword, definemethod allows you to generate methods at runtime, often based on data or logic that isn't known until the program is running. This provides a…
method_missing
methodmissing is a Ruby method that gets called when you try to invoke a method on an object that doesn't exist. Instead of raising a NoMethodError, Ruby gives you a chance to handle the missing method call yourself. This allows you to dynamically respond to method calls based on the method name and arguments…
Ruby DSL
A Domain Specific Language (DSL) is a programming language designed for a particular kind of application. Instead of being a general-purpose language that can solve a wide range of problems, a DSL is focused on solving problems in a specific domain, making code more readable and maintainable within that domain.…

It enables you to install, manage, and work with different Ruby versions (like Ruby 2.7, 3.0, or JRuby) and gemsets (isolated collections of gems) independently. This prevents conflicts…
Rbenv
Rbenv is a command-line tool that allows you to easily manage multiple Ruby environments (versions) on a single system. It works by intercepting Ruby commands and determining which Ruby version to use based on the current directory or a global setting. This enables you to work on different projects that require…
Stacks & queues
Stacks and queues are fundamental data structures used to manage collections of items. A stack operates on the Last-In, First-Out (LIFO) principle, where the last element added is the first one removed, like a stack of plates. Conversely, a queue follows the First-In, First-Out (FIFO) principle, where the first…
Search Algorithms
Search algorithms are methods used to find a specific element within a collection of data, like an array or a hash. These algorithms work by systematically checking each element in the data structure until the desired element is found or it's determined that the element is not present. Common examples include…
Sorting Algorithms
Sorting algorithms are methods used to rearrange a collection of items (like numbers, strings, or objects) into a specific order, such as ascending or descending. These algorithms work by comparing elements and swapping their positions until the entire collection is ordered according to the desired criteria.…
Recursion
Recursion is a programming technique where a function calls itself within its own definition. This creates a loop-like behavior, but instead of using explicit loops (like for or while), the function breaks down a problem into smaller, self-similar subproblems until it reaches a base case, which stops the recursion…
Blocks
Blocks are chunks of code that can be passed to methods as if they were arguments. They are defined using either do...end or curly braces {}. Blocks are not objects themselves, but they can be converted into objects called Procs. Methods can then execute the code within the block using the yield keyword. Blocks are…
Procs
A Proc in Ruby is an object that represents a block of code that can be stored, passed around, and executed later. Think of it as a named, reusable chunk of code. Unlike regular methods, Procs are objects, allowing them to be treated like any other variable, passed as arguments to methods, and stored in data…
Lambdas
Lambdas are anonymous functions, meaning they are functions without a name. They are objects in Ruby and can be treated like any other object, such as being passed as arguments to methods or stored in variables. Lambdas are defined using the lambda keyword or the shorthand - syntax, and they are similar to procs…
Stage 19: Concurrency
Concurrency
Concurrency and parallelism are techniques for improving the performance and responsiveness of programs by executing multiple tasks seemingly or actually at the same time. Concurrency deals with managing multiple tasks within a single program, allowing them to make progress even if one task is blocked. Parallelism,…
Defining Classes
A class is a blueprint for creating objects. It defines the attributes (data) and behaviors (methods) that objects of that class will possess. Defining a class involves specifying its name and the characteristics that its instances will have. This includes declaring instance variables to hold data and defining…
Instance variables
Instance variables in Ruby are variables that hold data specific to an object. They are defined within a class but belong to individual instances (objects) of that class. You create an instance variable by prefixing a variable name with an @ symbol (e.g., @name). Each object of the class will have its own copy of…
Attributes accessors
Attributes accessors provide a convenient way to access and modify the instance variables of a class. They automatically generate methods for reading (getting) and writing (setting) the values of these variables. The three main types are attrreader, which creates a getter method; attrwriter, which creates a setter…
Inheritance
Inheritance in Ruby allows a class (the subclass or derived class) to inherit properties and behaviors from another class (the superclass or base class). This promotes code reuse and establishes an "is-a" relationship. The subclass automatically gains the methods and attributes of the superclass, and can also add…
Modules & Mixins
Modules in Ruby are collections of methods, classes, and constants. They provide a way to namespace and prevent naming conflicts. Mixins allow you to incorporate module functionality into classes, enabling code reuse and multiple inheritance-like behavior. By including a module in a class, the class gains access to…
Pry

debug is a powerful debugging tool integrated directly into Ruby. It allows developers to step through code execution, inspect variables, set breakpoints, and evaluate expressions in real-time. This helps in identifying and resolving errors or unexpected behavior within Ruby programs.
Closures
A closure is a block of code that can be passed around and executed later, even after the scope in which it was originally defined has ended. It "closes over" its surrounding environment, capturing the values of variables that were in scope when the closure was created. This allows the closure to access and use…
Method Lookup
Method lookup is the process a programming language uses to determine which method to execute when a method is called on an object. It involves searching through the object's class and its ancestors (inheritance hierarchy) to find the appropriate method definition. The search typically starts with the object's…
Monkey Patching
Monkey patching is a technique that allows you to add, modify, or replace existing code in a class or module at runtime. This means you can change the behavior of classes and modules, even those defined in external libraries, without directly altering their source code. It's a powerful tool for extending…
Refinements
Refinements provide a way to modify the behavior of a class or module within a specific scope, without affecting the global definition of that class or module. This allows you to introduce changes or extensions to existing code in a localized manner, preventing unintended side effects in other parts of your…
Singleton Classes
A singleton class in Ruby is a special kind of class that is associated with a single object. It allows you to define methods that are specific to that particular object, without affecting other objects of the same class. Think of it as a way to add unique behavior to an individual object instance.
