i think he doesnt talk about his comments, he means that his solution isnt the shortest and could be better

I think you make some unneccessry comments and it actually makes your code hard to read. For example you don't need to say 'create an empty obj'. It is pretty obivious for anyone to know what you're doing.

nice! i missed the logic of checking if we were at the end of the string and adding the space. i tried to do it with template literals but then hit an error when the words array only had 1 word in it.

clever concept

love how my code took like 25 lines and 3 for loops and this guy solves it with 2 lines of code. fml.

what is this even doing?

Lol, I came to this discussion in hopes I would find someone had already asked this question. kudos to making my life easier sir. Thank you.

same exact solution xD

lol!!! += 1

love it! I'm always trying to think of ways to solve these problems like this but my brain isn't quite here yet. mines a bit longer but accomplishes the same task xD. Good job!

sorting wont work

It is not index, it is your array

getting better wont make up for piss poor explaination/description of problems

I knew this was possible but i wasn't sure exactly how to write it so I had to be a bit more lengthy with my answer. I had this in mind though. good answer.
