A few days back, I published a list of 650+ frontend interview questions.
That post got attention, feedback, and a surprising amount of messages from developers (both junior and senior) telling me it helped them prep better.
But something didn’t feel complete.
Because questions alone are not enough.
So I continued learning deeply, exploring each topic, facing more interviews, reading docs, breaking code, and then documenting the patterns I found.
And that small side note list turned into something else completely.
What’s new in v2.0?
- 1,020+ questions with detailed answers
- 185+ coding problems (each solved step-by-step)
- 600+ flashcards for fast revision
- new sections: TypeScript, Security, Testing, Tooling
- difficulty tags, interview frequency, company tags
- code examples + common mistakes + time to answer estimates
This is no longer “a question bank”.
This is a complete frontend mastery system.
GitHub Repo
📘 Frontend Master Prep Series v2
https://github.com/maurya-sachin/Frontend-Master-Prep-Series
Open-source. Free. Well-structured.
Use it in VS Code / Obsidian / Notion.
Why this matters
Most interview prep content online is too shallow.
It teaches the what.
But senior interviews check the why.
Why does React re-render?
Why does this promise resolve later?
Why Next.js instead of client-side React?
This project grew because I kept asking that exact question myself.
What’s next?
I’m currently working on:
- a Notion version with progress tracking
- a PDF cheat sheet for 1-day revision
- a “Roadmap style” resource guide by topics
Why I built this
To be honest — I built this for myself first.
Because I wanted to really understand this craft.
But if even one developer somewhere uses this repo and gets more confident before their next interview —
then this work is already worth it.
If you find this useful — consider giving a ⭐ to the repo.
That’s how I’ll know this should continue growing.
