To get n number of last items from an array in JavaScript, simply pass a negative value to Array.slice:
Copied to clipboard! Playground
const array = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
// This will return [9]
console.log(array.slice(-1));
// This will return [8, 9]
console.log(array.slice(-2));
// This will return [7, 8, 9]
console.log(array.slice(-3));If you only interested in the returned value, you can also unwrap it with pop:
Copied to clipboard!
// This will all return 0
array.slice(-1)[0];
array.slice(-1).pop();
array[array.length - 1];In case your array is empty, undefined will be returned.
