I Added JavaScript & Python Sections to My TypeScript Quiz – Here’s What Happened

Tue, 12 May 2026 12:29:03 +0000

A few weeks ago I launched TS Quiz — a free quiz to help developers test their TypeScript skills.

The response was great, but many people asked for something broader.

So I added JavaScript and Python sections.

What TS Quiz Offers Now:

125+ questions across multiple languages
5 difficulty levels
Strong focus on TypeScript and React + TypeScript
Brand new JavaScript and Python sections (selectable in the top right)
AI-powered feedback that analyzes your results and gives personalized recommendations

No login required. Completely free.

Why I Built This

I wanted a single place where developers (especially beginners and intermediate) could test their skills across the languages they actually use daily.

Whether you're learning frontend (TypeScript/React), improving your JavaScript fundamentals, or exploring Python — you can now practice in one place.

15 Tricky TypeScript Questions That Stumped Me (And the Quiz I Built)

I thought I was pretty good at TypeScript… until I kept getting destroyed by questions on generics, conditional types, and mapped types.

After getting frustrated with existing quizzes, I decided to build my own.

TS Quiz

A free interactive quiz with 125 questions across 5 difficulty levels:

Basic
Intermediate
Advanced
Functional Programming
React + TypeScript

It also includes new JavaScript and Python sections.

What makes it different? After finishing, an integrated AI analyzes your results and gives personalized feedback on your weak areas.

How Good Are You actually at TypeScript? I Built a Quiz to Find Out

We've all been there.

You finish a tutorial, understand the concepts, and think "Yeah, I got this".

But when it comes to real code... things get tricky.

So I decided to build something to answer the question honestly.

Introducing TS Quiz

A free interactive quiz platform with:

125 questions across 5 difficulty levels
Basic, Intermediate, Advanced
Functional Programming with types
React + TypeScript dedicated section
Newly added JavaScript and Python sections

What makes it different?

Most quizzes just give you a final score and that's it.

TS Quiz goes further: after finishing, an integrated AI analyzes your performance and tells you:

Your weak areas
Why certain concepts tripped you up
What you should study next

Topics Covered

Generics & advanced typing
Utility types
Conditional and mapped types
Declaration merging
React patterns (props, hooks, context, etc.)
Many real-world tricky scenarios

No login required. Completely free.

Try it yourself:

I’d love to know:

What score did you get?
Which section was the hardest for you?
Any topics you think are missing?

This project is evolving fast based on community feedback, so every comment helps make it better.

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

Tue, 05 May 2026 08:06:25 +0000

Hey devs,

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.

So I built TS Quiz — a free interactive quiz platform focused on modern TypeScript and React + TypeScript.

What’s inside?

125 hand-crafted questions
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
- And many tricky real-world scenarios

No login or signup required. You get instant scoring and it clearly shows which areas you need to focus on.

I made this because I believe one of the fastest ways to improve is knowing exactly where your weak spots are — not just guessing.

Try it here:

👉 https://www.ts-quiz.com/

Would 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 it 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 👇

Happy coding!

I built a free TypeScript quiz website with 125 questions and levels

Thu, 30 Apr 2026 11:00:21 +0000

Over the last few weeks I have been working on a small side project to help people improve their TypeScript skills in a more practical way. I always felt that just watching tutorials or reading documentation was not enough, so I ended up building this:

https://www.ts-quiz.com/

Some features it includes:

5 levels, such as basic, medium, advanced, functional and React

It has 125 questions (for now)

It focuses on concepts like types, narrowing, generics and so on

You get feedback while answering

The stack I used is React and TypeScript and the user interface is simple since it's mostly focused on usability and learning rather than design.

I have some ideas for the future such as:

Progress tracking

Score system

Leaderboards
