► The shift() method is similar as the pop() method but the difference is that Shift method works at the beginning of the array.

► The shift() method take the first element off of the given array and returns it. The array on which is called is then altered.

► For example :

var myarray = ["apple ", "banana ", "mango "];

console.log(myarray.shift());

console.log(myarray);

► We get the following console output :

apple

["banana ", "mango "];

► When we call shift() on an empty array, it will return an undefined value.
