javascript adding item shift code example

Example 1: array shift javascript

//The shift() method removes the first element from an array 
//and returns that removed element. 
//This method changes the length of the array.

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

Example 2: js get first item from array

var colors = ["red", "green", "blue"];
var red=colors.shift();
//colors is now ["green","blue"];
