I am beginner who thought before doing the String Methods section of the course "You know what, let's test my skills". And boy my skills were tested. After I completed the challenge my jaw dropped, with the solution.
Had/Have this happened to y'all. Where you make something complicated and found out that there was a simple solution?
Solution
My Code
(For point 1) Got it, from now on variables will be declared with
let. I don't understand what is"use strict";maybe you can explain it.(For point 2) I was testing to see if
reversedWordprinted the desired output in the Console, forgot to remove it after finishing the program. I also don't understand what 'O(N^2)' and 'O(N)' is, but+=-ing an empty string is a great idea, why didn't i think of that."use strict";is just a way of enabling more restrictions to make writing JS less error prone. You can find the details of what that does on MDN (or, if you don't like long verbose technical explanations, this is a pretty good summary!)
