Mastering the push() Method in JavaScript ➕

The push() method in JavaScript allows you to add one or more elements to the end of an array and then returns the new length of the array. It's considered a mutating method because it changes the original array.

🔍 Try this example in the console yourself: 
Press `F12` to open the developer tools, navigate to the ‘console’ tab, and paste the code provided below. Press `Enter`, change the numbers, and play around with the code to see different results!

<pre class="preFormatted"><code class="codeFormatted">
const array1 = [1, 2, 3, 4];
const newLength = array1.push(5, 6);
console.log(array1); 
// output: [1, 2, 3, 4, 5, 6];
</code></pre>

As you can see, the `push()` method adds the elements 5 and 6 to the original array and returns the updated array!
