Credits & Attribution
JS Questions Lab is a creator-built practice product. The original questions and explanations come from Lydia Hallie's javascript-questions. My contribution is the product layer: the interface, runner, visualization, scratchpad, and progress loop that make the material feel more usable in real practice sessions.
This page extends the original credits, it does not replace them. The upstream source references and supported language listing stay preserved below.
Why I Built It
Lydia's repository is one of the best JavaScript references on the internet, but interview prep usually needs a faster loop than reading a long markdown file. I built this so you can answer first, reveal second, run code immediately, and come back with progress that still means something.
This project is also personal proof-of-work. I wanted the site itself to show care: design restraint, faster interactions, better mobile ergonomics, and a clearer sense that someone is actively making the experience better.
