Remove Last Item From Array in JavaScript

Another way to change the data in an array is with the .pop() method.

.pop() removes the last element of an array and also returns the value of that element:

let threeArr = [1, 4, 6];

// Remove last element:
let oneDown = threeArr.pop();

console.log(oneDown); // Output: 6
console.log(threeArr); // Output: [1, 4]

// Remove last element again:
let oneDown = threeArr.pop();

console.log(oneDown); // Output: 4
console.log(threeArr); // Output: [1]
