Reverse a String: Why Am I Not Passing?

Tell us what’s happening:
I don’t know why I’m not passing this challenge. Every phrase I’ve entered in the function has reversed correctly, including the test ones.

  **Your code so far**

function reverseString(str) {
str = [...str]

for (let i = (str.length-1); i >= 0; i--){
  let popped = str.pop()
  str.splice((str.length - i),0,popped)
  str = [...str]

str = str.toString();

let regex = /,/g;
let removed = ''
str = str.replace(regex,removed);

Challenge: Reverse a String

Link to the challenge:

OK it was literally just because I was missing a return statement. Since I was seeing everything show up in the console I was confused.

Was looking at this for ages and of course only realized right after posting :man_facepalming:

Welcome to coding. :grinning: Wait 'til you spend three days looking for a missing semicolon!

Glad you found the error.

OP, I’m glad you solved the problem on your own. That said, you’ve got some weird stuff going on.

Remember that you can access characters of a string via their index.

const name = "Colin"

console.log(name[2]) // "l"

In your code you’re needlessly converting between the string to an array and back to a string again. You absolutely do not need to do this.

Remember also that you can build up a string using the += operator to append one string to another.

let name = "C";
name += "o";
name += "l";
name += "i";
name += "n";

console.log(name) // "Colin"

What I’m saying is, you’re overcomplicating this quite a bit. You can solve this problem with just a for loop and string concatenation.
