JavaScript Array
The array is a data structure that is used to store data in a sequential manner of the same type. Arrays allow duplication of data and data is indexed which means that the data can be accessed according to its unique index.
Syntax:
let arrayName = [value1, value2, ...]; // Method 1
let arrayName = new Array(); // Method 2
Example: In this example, we will implement an array and access its element.
Javascript
let sample = new Array();sample.push("Hello");sample.push("1")sample.push("Bye")sample.push("@");console.log(sample);console.log(sample[3]) |
Output
[ 'Hello', '1', 'Bye', '@' ] @
