What is Array?
An array is a data structure that stores an ordered collection of elements, where each element is accessed using its numerical index. Arrays are fundamental for managing lists of items, and in TypeScript, you define the types of elements that an array can hold, enforcing consistency and preventing errors. An array's length is mutable allowing you to dynamically add or remove elements.
