This is how I did it but I used a ternary operator

Oh I never saw that one, thanks you for reply !

Hi! This is a shorter way of accessing the .charAt() method on a string. Take a look at the docs here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String#character_access

Hi! Beginner here, I thought [] was for the array only. Why, can we use [] for the string "name" here? Sorry for my bad english.

I mean, as far as solving the solution without using any built-in methods goes, this works well.

Oh! Thanx, I think i se now

They add space for all of each word, except word in last index of array (words.length-1)

I can't get, what's doing those lines of code:
if(i!=words.length-1) {
smashed += ' ';
}
Could you explain it to me pls ?

Anyway you get an unnecessary space at the start of smashed string, don't you ?

This is more or less how I did mine. The only difference is that I used string interpolation instead.

In general a good practice is to avoid unnecessary code, but sometimes it's better to write more for readability.

Isn't also a best practice not to have multiple return statements when not necessary?

It's not a good practice to put else statement after return.

Interesting approach!
