hello everybody :grinning:
i’m having more or less the same problems.
all the steps pass untill i put the code for the alphanumeric palindrome.
when i paste the code for alphanumeric palindrome

function isPalindrome(str) {
    // Remove non-alphanumeric characters and convert to lowercase
    str = str.replace(/[^0-9a-z]/gi, '').toLowerCase();

    // Compare characters from the start and end of the string
    // and stop if a mismatch is found or the middle of the string is reached.
    for (let i = 0; i < str.length / 2; i++) {
        if (str[i] !== str[str.length - i - 1]) {
            return false;
        }
    }

    return true;
}

// Prompt the user for input
checkButton.addEventListener('click', () => {
    const inputText = inputField.value.trim();

    if (inputField.value === '') {
        resultDiv.textContent = 'enter some text';
        return;
    }

    // Output the result
    if (isPalindrome(inputText)) {
        resultDiv.textContent = `"${inputText}" is a palindrome.`;
    } else {
        resultDiv.textContent = `"${inputText}" it is not a palindrome`;
    }
});

any suggestions?

I have your post into a new thread. It’s best to make your own thread instead of taking over someone else’s.

This doesn’t look like an exact, word for word match of the requested message

4

thank you
I appreciate

5

do you think the problem is only the word for word match?
I mean , is the code correct?
why without that last bit of code, all the steps pass the test and dont pass with that piece of code?
that is one of the thinks I
dont understand…

I don’t know if it’s the only problem. I just saw a problem

remove the quotes

remove the quotes and fix the wording

the output needs to be exactly as requested

8

remove the quotes…?
do you mean the `` quotes?

what is the difference?
i’m not sure I understood whay and when those quotes are necesary or not.
can you explain?

They’re not necessary because you’re already using template literals which serve as a form of quote if you get what i mean

i removed the quotes " ----"
changed some words and passed all the steps.

    // Output the result
    if (isPalindrome(inputText)) {
        resultDiv.textContent = `${inputText} is a palindrome.`;
    } else {
        resultDiv.textContent = `${inputText} is not a palindrome`;
    }
});

I understand what you mean.

thank you.
