Array

JavaScript array is a special data structure to store ordered values. It can be written as values, or items, separated by commas inside of square brackets:

[item1, item2, item3]

Declaration

Using an array literal is the easiest way to create a JavaScript array.

We can declare an empty array:

let e = [];

We can supply initial elements in the brackets:

let fruits = ["Apple", "Orange", "Banana"];
let myArray = [2, 4, 6, 8];
let studentRecords = ['Bella', 'Math', 98];

An array can store elements of different types like in the last example.

Arrays have some characteristics similar to strings, including indexing, looping, the length property, and addition and multiplication operations.
