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!
Code
const array1 = [1, 2, 3, 4];
const newLength = array1.push(5, 6);
console.log(array1);
// output: [1, 2, 3, 4, 5, 6];As you can see, the push() method adds the elements 5 and 6 to the original array and returns the updated array!
