   Rishabh Tandon – June 27, 2026

   I was preparing for frontend interviews and wanted something that covered real JavaScript problems instead of just theory. This guide was exactly what I needed. The scenario-based questions and code examples helped me understand closures, promises, async/await, event loop, prototypes, and ES6 concepts in a much more practical way. Several questions were very similar to what I faced during my interviews. It helped me perform with confidence and land a great frontend developer role.
