JavaScript Arrays: A Comprehensive Guide

In JavaScript, an Array is a special variable used to store multiple values in a single variable. Arrays are dynamic, meaning their size can change, and they can hold different types of data.

Creating an Array:

Using Array Literal (Preferred way)
Using new Array() Constructor
Empty Array Initialization

Using Array Litera Example

let fruits = ["Apple", "Banana", "Cherry"];

Using new Array() Constructor Example

let numbers = new Array(1, 2, 3, 4);

Empty Array Initialization Example

let emptyArray = [];

Accessing Array Elements:

Array elements are accessed using index numbers (0-based indexing).

Example

let fruits = ["Apple", "Banana", "Cherry"];

console.log(fruits[0]); // Apple

console.log(fruits[1]); // Banana

Try it yourself
