Create a new Array JavaScript | Example code

  • by

Using an array literal is the easiest way to create a new Array in JavaScript. There is no need to use the new Array() way to create Array.

const array_name = [item1, item2, ...]; 

// Using array literal notation
let myArray = []; 

// Using Array constructor
let myArray2 = new Array(); 

You can also create an array and then assign the elements.

const cars = [];
cars[0]= "AAA";
cars[1]= "BBB";
cars[2]= "CCC";

Array constructor with multiple parameters

If more than one argument is passed to the constructor, a new Array with the given elements is created.

let fruits = new Array('Apple', 'Banana');

console.log(fruits.length); // 2
console.log(fruits[0]);     // "Apple"

You can access and modify elements in the array using their index. The index starts from 0, so the first element is at index 0, the second at index 1, and so on. Here’s an example:

let myArray = [1, 2, 3, 4, 5];

console.log(myArray[0]); // Output: 1

myArray[2] = 10;
console.log(myArray); // Output: [1, 2, 10, 4, 5]

These are just the basics of creating and working with arrays in JavaScript. There are many other operations and methods available for arrays, such as push, pop, splice, and more.
