Tell us what’s happening:

I cannot find an error in this to save my life. Also I’m 99% sure it isn’t suppose to be if (!["+","-"," "].includes(strArray[i])).

I am 99% sure it should be if (!strArray.includes(["+","-"," "])). Is that correct or am I wrong? Either way, what will get the code to pass?

Your code so far

function cleanInputString(str) {
  const strArray = str.split('');
  const cleanStrArray = [];
  }

  for (let i = 0; i < strArray.length; i++) {
     if (!["+","-"," "].includes(strArray[i])) {
       cleanStrArray.push(strArray[i]);
       
  }
}

Make sure your curly brackets are in the right places

Hey @craegan15 and welcome to the FCC community!

You have an extra curly brace above the for loop that is causing an error. All the rest of your code is correct!

4

That bracket goes with the function cleanInputString

5

This bracket is causing issues because it ends the function and then you have a for loop that’s now outside of the function.

I try to remove it and it still doesn’t work. I also try to put it after the for loop and it doesn’t work

7

Please post the updated code because moving it outside the for loop is what you should have done.

I know but it still won’t work):
updated code:

function cleanInputString(str) {
  const strArray = str.split('');
  const cleanStrArray = [];

  for (let i = 0; i < strArray.length; i++) {
     if (!strArray.includes()) {
       cleanStrArray.push(strArray[i]);
    }
  }
}

This line is now incorrect for a couple reasons. There is nothing in the includes() method, and the order is reversed for what to check.

You should be checking the ["+","-"," "] to ensure that the current character is not a part of this array.

You had it correct here:

if (!["+","-"," "].includes(strArray[i])) {

But you changed it which is why it is no longer working. Remember, you want to check that the array containing the plus, minus, and space does not contain the current character we’re checking.
