Examples

The pop() is a JavaScript pre-built method that removes the last element from an array and returns that element. This method changes the length of the array.

There is no point in memorizing all the pre-build functions in a programming language, as there may be hundreds or even thousands of them and they get easily deprecated. Is way more advisable lo invest time in exploring the documentation and learning to use it faster while coding.

The following code creates the myFish array containing four elements, then removes its last element.

const myFish = ['angel', 'clown', 'mandarin', 'sturgeon'];
const popped = myFish.pop();
console.log(myFish); // ['angel', 'clown', 'mandarin' ]
console.log(popped); // 'sturgeon'
