JavaScript array is used to store multiple elements in a single variable. It is often used when we want to store a list of elements and access them by a single variable. Unlike most languages where the array is a reference to the multiple variables, in JavaScript, an array is a single variable that stores multiple elements.
Syntax:
let array = [value1, value2, ...];
let array = new Array();
Example 1: Here is the basic example of an array in javascript.
Javascript
// Declaring an array using Literal Notation let language = ["HTML","CSS","Javascript"] console.log(language) |
Output:
['HTML', 'CSS', 'Javascript']
Example 2: In this example, we are using a new keyword.
Javascript
// Declaring an array using Array Constructor let language = new Array(3) language[0] = "HTML"language[1] = "CSS"language[2] = "Javascript"console.log(language) |
Output:
['HTML', 'CSS', 'Javascript']
