I’m aware of theses questions (1) and (2).
But i would like why push method returns array length but pop method returns value that has been removed, even though both methods seems very similar in opposite way.

Here an example code:

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

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

console.log(plants.push("Onion"));
// Expected output: 5

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