js return array without first element 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: es6 remove first element of array

var myarray = ["item 1", "item 2", "item 3", "item 4"];

//removes the first element of the array, and returns that element.
alert(myarray.shift());
//alerts "item 1"

//removes the last element of the array, and returns that element.
alert(myarray.pop());
//alerts "item 4"
