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 👇
