About JSPrep Pro

JSPrep Pro is an independent frontend interview practice platform, built and run by Yash Maheshwari.

What it is

Frontend interviews often test more than definitions, so JSPrep Pro lets you practice explaining concepts, predicting code output, fixing bugs and writing polyfills, with AI feedback on your answers. It includes 500+ questions and 80+ topic guides across JavaScript, React, TypeScript and frontend system design.

What to expect

AI feedback is a practice tool, and it can be wrong. We can't promise interview results, and we don't claim to know which company asks which question unless we can show evidence for it.
