//Array.shift() removes the first array element and returns it value
//example 1
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
var arr = ["f", "o", "o", "b", "a", "r"];
arr.shift();
console.log(arr); // ["o", "o", "b", "a", "r"]
