How do you build a local search filter in HTML/JS without querying the database?

I have a large table of Q&A data loaded into the DOM. How do I write a fast Javascript function to filter the rows instantly as the user types?

Attach an 'input' event listener to your search bar. In the function, grab the search string, convert it to lowercase, and use document.querySelectorAll('tr') to loop through table rows. Use textContent.includes() to check for matches, toggling display: none on rows that fail the check.
