Array.prototype.pop()

The pop() method removes the last element from an array and returns that element. This method changes the length of the array.

const plants = ['broccoli', 'cauliflower', 'cabbage', 'kale', 'tomato'];

console.log(plants.pop());
// expected output: "tomato"

console.log(plants);
// expected output: Array ["broccoli", "cauliflower", "cabbage", "kale"]

plants.pop();

console.log(plants);
// expected output: Array ["broccoli", "cauliflower", "cabbage"]
