JavaScript Array Exercise

Last Updated : 5 Aug, 2025

In JavaScript, an Array is a versatile data structure that allows you to store multiple values in a single variable. Arrays can hold different data types, including strings, numbers, objects, and even other arrays. JavaScript arrays are dynamic, which means they can grow or shrink in size.

JavaScript
let a = ["apple", "banana", "cherry"];
console.log(a);

Output

[ 'apple', 'banana', 'cherry' ]
