01

The problem

JavaScript and React interview prep is scattered across docs, blog posts, and random question lists, with no single place to learn a topic in depth, test recall, and practice code in one flow.

02

What I built

  • Built a public platform with 40 JavaScript topics and 17 React topics, all in MDX content.
  • Each topic carries an overview, examples, in-depth notes, interview Q&A, and a playground.
  • Added output prediction and coding challenges alongside the Q&A, so recall gets tested, not just read.

03

Outcome

A live, public learning platform for JavaScript and React interview prep.
