How to get last element of an array or string using JS ES13 Feature


Javascript ES13 has released in June 2022 and it has pretty cool new features one of them is at() method that can be used with strings and arrays.

So, before ES13 if you want to find the last element of an array or string.

You need to subtract 1 from the length of the array and string and the calculated value will be passed within [] to get the last element like this 👇

I won't lie, doing this daily seems hectic and I really would not recommend it to everyone. But it's super addictive to me, it's become a daily routine, and I can't see myself not doing it.

const name = "Sam";
console.log(name[name.length - 1]) // "m"

const names = ["Ram", "Sam"];
console.log(names[names.length - 1]) // "Sam"

But now, after ES13 you can use at() method with negative indexes to get the elements in reverse order of a string or array like this 👇

const name = "Sam";
console.log( // "m"

const names = ["Ram", "Sam"];
console.log( // "Sam"

Simple right?
