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


example:

var colors = [ 'red','white', 'blue'];

colors.shift(); 
console.log(colors)

// colors = [ 'white', 'blue']

var numbers = [1, 2, 3, 4, 5];
numbers.shift();

console.log(numbers);
//  numbers: [  2, 3, 4, 5 ]
