Last Index Value Of Array Javascript/TypeScript

Hey everyone, I usually give thought to how can I make my and other's life easy, so came up with the idea to write articles.
Getting to the point, I came across a life hack for arrays. Finding the last index value in an array was always like using the array's length and subtracting 1 from it(As the array gives length like normal daily like counting, whereas arrays start with 0 indexes).


let array = [3,4,5,6,7];
let lastElement = array[array.length - 1];
console.log(lastElement); // prints 7
Enter fullscreen mode Exit fullscreen mode

So whats the way around? Here it is 😁😁

let array = [3,4,5,6,7];
let lastElement =;
console.log(lastElement); //prints 7
Enter fullscreen mode Exit fullscreen mode

Just keep going reverse, you can get all elements of the array. Don't forget a condition to avoid going out of indexes as it'll give you undefined.

Feel free to comment to add more information to this article. Happy Coding.
