Checkpoint

At this point you should be able to add interactivity to your web pages using JavaScript. You should make sure that you have learnt the following:

• Know about variables, loops, data types, conditionals, functions.
• Know about arrays and objects and different ways to access their data.
• Know how to select DOM elements.
• Add event listeners to DOM elements (e.g. click, focus, form submission).
• Use JavaScript to add and remove DOM elements
• Add and remove classes from DOM elements
• Use JavaScript to make HTTP requests to external APIs (i.e. fetch)
• Use JavaScript to store data in the browser's local storage

Here are few ideas to practice your skills:

• Create a simple to-do list app that allows users to search, add, edit, and delete items. Use local storage to store the data.
• Create a simple webpage where user can put in anyone's GitHub username and see their profile information. You can use GitHub's API to fetch the data. For example, here is the sample URL to fetch my data. Make sure to add validation and error handling.
• Create a basic calculator app that allows users to perform basic arithmetic operations.
