JS: unshift() Method

Sometimes you must push an element at the front of the array. This is not possible with the regular push() method of the array class.

Fortunately, JavaScript has a function called unshift() that push the elements at the front of the array.

The shift method can be used to push

  1. single element
  2. two or more element
  3. a sub array

In this example, we will try to push a single element and a sub-array to a JavaScript array.

Consider the following example.

var myArray = new Array(23,44,5.5,'tomato');
myArray.unshift("pen");
myArray.unshift([23,66]);
console.log(myArray)

The output of the above script is given below.

[[23,66],"pen",23,44,5.5,'tomato']
