Tell us what’s happening:

I’m trying to integrate the regex example presented in this step and I need help doing that

Your code so far

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

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

The challenge seed code and/or your solution exceeded the maximum length we can port over from the challenge.

You will need to take an additional step here so the code you wrote presents in an easy to read format.

Please copy/paste all the editor code showing in the challenge from where you just linked.

Replace these two sentences with your copied code.
Please leave the ``` line above and the ``` line below,
because they allow your code to properly format in the post.

I think you are trying to do more than the instructions are asking.

“Remove your existing code within the cleanInputString function.”

This means get rid of everything inside of the cleanInputString function. It should be completely blank.

“Declare a regex variable and assign it the value from the example above.”

This means you should add one line which declares the variable regex and give it the same value as in the example in the instruction. In other words, copy the code from the example into the cleanInputString function.

That’s all you need to do.

I think the word regex threw me off and thereby I became confused because it is the first time I see it.
