pop()

Remove from the end of an array

Goal

Learn to remove the last element of an array using pop().

Explanation

  • pop() removes the last element of an array.
  • After pop() is called, the array becomes shorter.
  • The method changes the original array.
  • It specifically removes the last element.
  • pop() is often used when working with a stack of data.

Analogy

Imagine a stack of plates. pop() removes the top plate from the stack.

Code

const fruits = [
  "Apple",
  "Banana",
  "Orange"
];

fruits.pop();

console.log(fruits);

Result: ["Apple", "Banana"]

Common mistake

Beginners sometimes think pop() removes the first element. In fact, it only works with the last one.
