Tell us what’s happening:
Hello everyone,
I’m currently working on the Palindrome Checker project in the JavaScript Algorithms and Data Structures Certification course on FreeCodeCamp. I’ve written a solution that seems to work correctly when I manually test it with various inputs. It correctly identifies palindromes and non-palindromes and returns the expected true/false values.
However, I’m encountering an issue where my solution isn’t passing the automated tests on FreeCodeCamp. Every time I run the tests, it fails, even though the manual checks with the same inputs pass flawlessly.
I’ve tried debugging and checking for common pitfalls, such as case sensitivity and non-alphanumeric characters, but haven’t been able to identify the cause of the issue. I’m wondering if there might be a specific format or an edge case that I’m overlooking, which is required by the FreeCodeCamp testing suite.
