I just shipped v2.0 of Frontend Master Prep Series — 1,020+ Q&A + 185 coding problems + 600 flashcards

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.
