How to create a array in JavaScript?

An array is a non-primitive data type that allows you to store multiple values of different or similar data types at consecutive memory blocks in a single variable. The values stored in an array can be accessed using the indexing syntax starting from zero and going to the array.length-1.

Different ways of creating an array in JavaScript are listed below:

• Using array literal: It is the simple square brackets syntax that is generally used to create arrays in programming languages.
• Using Array constructor: JavaScript provides us with an array constructor to create arrays.

Example: The below example shows how you can create a simple array in JavaScript.

Javascript

// Creating array using array literals
const myArr1 = ["GFG", 254, true, "JavaScript"];
console.log(myArr1[0], myArr1[2], myArr1);

// Creating array using array constructor
const myArr2 = new Array("GFG", 2, true);
console.log(myArr2[1], myArr2[2], myArr2);

Output

GFG true [ 'GFG', 254, true, 'JavaScript' ]
2 true [ 'GFG', 2, true ]
