This post is a note that includes my thoughts about something I found online. Check it out yourself!

I just saw that Array.prototype.at will ship in Chrome 89 and Firefox 85. How do I know? I'm watching the MDN browser combat data repo on GitHub. 🙈

const numbers = [1, 2, 3];

// old way to access array elements from the end
numbers[numbers.length - 1]; // 3

// new way to access array elements from the end
numbers.at(-1); // 3

That's a welcome addition to the language! 🎉
