I Built a Free TypeScript & React Quiz with 125 Questions – Test Your Real Skills

Source: Dev.to

Overview

After spending a lot of time writing TypeScript code (and sometimes feeling more confident than I probably should), I decided to create something to help myself and others properly measure their TypeScript knowledge.

Features

• Free, interactive quiz platform focused on modern TypeScript and React + TypeScript.
• 125 hand‑crafted questions across 5 difficulty levels (Basic → Advanced).
• Topics include:
  • Core TypeScript concepts
  • Generics and Utility Types
  • Conditional Types & Mapped Types
  • React + TypeScript (props, hooks, context, etc.)
  • Functional programming patterns with types
  • Many tricky real‑world scenarios
• No login or signup required.
• Instant scoring with clear indication of areas that need improvement.

How to Use

Visit the quiz at:

1. Start the quiz – no account is required.
2. Answer the questions; the platform tracks your score in real time.
3. Review the results to see which topics you should focus on.

Feedback

I’d love honest feedback from the community:

• Did any questions feel unclear or incorrect?
• Are there important topics missing?
• Too easy / too hard in certain sections?

I’m actively improving the quiz based on feedback, so every comment helps. If you work with TypeScript or React, give it a shot and let me know your score in the comments below.

Happy coding!
