What is Shift() method in Javascript?

Answer

-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.
