Manipulating Arrays

Learn how to add and remove elements from an array.

We'll cover the following...

Adding elements to the beginning or end

You can add elements to the beginning and to the end of the array:

  • Push adds elements to the end of the array
  • Unshift adds elements to the beginning of the array
Node.js
let days=['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday'];
days.push( 'Saturday' );
console.log("Saturday is added to the end by the push() function\n", days ); 
days.unshift( 'Sunday' ); 
console.log("Sunday is added to the beginning by the unshift() function\n", days );
