shift unshift code example

Example 1: array.unshift in javascript

//The unshift() method adds one or more elements to the beginning of an array 
//and returns the new length of the array.

const array1 = [1, 2, 3];
console.log(array1.unshift(4, 5));
// expected output: 5
console.log(array1);
// expected output: Array [4, 5, 1, 2, 3]

Example 2: unshift method in javascript

var name = [ "john" ];
name.unshift( "charlie" );
name.unshift( "joseph", "Jane" );
console.log(name);

//Output will be
[" joseph "," Jane ", " charlie ", " john "]

Example 3: 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)
