understanding js push,pop,shift,unshift code example
Example 1: shift and unshift js
let cats = ['Bob', 'Willy', 'Mini'];
cats.shift(); // ['Willy', 'Mini']
let cats = ['Bob'];
cats.unshift('Willy'); // ['Willy', 'Bob']
cats.unshift('Puff', 'George'); // ['Puff', 'George', 'Willy', 'Bob']
Example 2: 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)
