When an item is added to or removed from the array, the length property is updated. You can check this by running this code:
const array = [1, 2, 3]; array.length = 100; console.log(array.length) //=> 100
length NEEDS to be a property, otherwise code like this would become exponential:
length
for (let i = 0; i < input.length; i++) { }
