Arrays in JavaScript are used to store multiple values in a single variable, providing an efficient way to group and manage data. They are particularly useful for storing lists of items, such as numbers, strings, or objects, where each item can be accessed and manipulated using an index.

Why to Use Arrays?

Arrays provide a way to store multiple items in a single variable, making it easier to collect, access, and manipulate data.

Example: Comparing Variables to an Array

Imagine we want to store a list of fruit names.

Without an array:

let fruit1 = "apple";
