const textInput = document.getElementById("text-input");

checkBtn.onclick = alert;
 
 function alert() {

     alert("Please input a value");
   } else {
      palindrome()
   }
 }

const palindrome = () => {
  const newstr = textInput.value.toLowerCase().match(/[a-z0-9]/g).join('')
  const compstr = textInput.value.toLowerCase().match(/[a-z0-9]/g).reverse().join('')
  if(newstr === compstr) {
result.innerText = `${textInput.value} is a palindrome`
return textInput.value
  } else {
result.innerText = `${textInput.value} is not palindrome`
return textInput.value
 }
}

After fiddling with your code and scratching my head as to why tests wouldn’t pass… it came down to some missing characters in your return string.

Try:

result.innerText = `${textInput.value} is not a palindrome`

I was able to pass the tests with your code after that adjustment.

thanks for the help still wont pass im kinda lost

Weird. I copied your html, and script exactly. I put those into the project, and the only text I changed was:

result.innerText = `${textInput.value} is not palindrome`

To:

result.innerText = `${textInput.value} is not a palindrome`

And your code was able to pass all the tests. Try copying your work, and resetting the project.

will do see what happends

dude im a dumbass they were both the same lol

thank for all your help cant believe i did that at this for hours
