Build a Palindrome Checker Project - Build a Palindrome Checker

Tell us what’s happening:

The “When the #text-input element only contains the letter A and the #check-btn element is clicked, the #result element should contain the text ‘A is a palindrome’.” Check and all similar checks aren’t reading my result element’s text even though it’s clearly there on the preview screen.
