// example:
let yourArray = [2, 3, 4];
yourArray.unshift(1); // yourArray = [1, 2, 3, 4]
// syntax:
// <array-name>.unshift(<value-to-add>);unshift method in javascript
var name = [ "john" ];
name.unshift( "charlie" );
name.unshift( "joseph", "Jane" );
console.log(name);
//Output will be
[" joseph "," Jane ", " charlie ", " john "]shift and unshift js
let cats = ['Bob', 'Willy', 'Mini'];

/*The unshift() adds method elements to the beginning, and push() method
adds elements to the end of an array.*/
let twentyThree = 'XXIII';
let romanNumerals = ['XXI', 'XXII'];
romanNumerals.unshift('XIX', 'XX');
// now equals ['XIX', 'XX', 'XXI', 'XXII']
romanNumerals.push(twentyThree);
// now equals ['XIX', 'XX', 'XXI', 'XXII', 'XXIII']js unshift vs push
//My Opinion is really nothing. They are the same exept one adds a element
//to the end and the other one adds a element to the front
// Push Method
var array = [2];//your random array
array.push(3)
// Unshift Method
array.unshift(1)Copyright © 2021 Codeinu
