Array shift() Method

The Array shift() method removes and returns the first element of an array and shifts the indexes of the remaining elements one lower. The syntax for this method is

			array.shift(); 
			

We consider an array named os consisting of four elements

			var os = ["Debian", "Fedora", "openSUSE", "Ubuntu"];
			

Applying the shift() method on it will remove and return its first element Debian, which is assigned to the variable first

			var first = os.shift();
			

and the new modified array with one element less becomes

			["Fedora", "openSUSE", "Ubuntu"];
			

The variable first holds the returned value Debian.
