The Most Important Skill for a Developer
The internet is full of JavaScript learning content: courses, books, videos. Most of it focuses on writing code, but in real work most of the time is spent reading and debugging code — either your colleagues’ code or your own from months ago. That’s what led us to build a tool that teaches JavaScript in a different way.
How Debugit Changes the Learning Process
Here’s what a typical JavaScript exercise looks like:
Exercises like this are dull. They are nothing like real developer work.
Debugit works differently. The code is already written, documented, and covered by tests. But not all tests are green — there’s a bug inside. Just like in real projects, tests don’t always pass.
Each exercise has one goal: find and fix the bug. Debugit gives you the tools to do this right in the browser: run tests, edit the code, experiment in a playground.
This approach is far more effective than memorizing theory. You learn by forming hypotheses, testing them, and exploring the language. That way, what you learn stays with you.
Closer to Real Code
Debugit avoids the trap of toy examples. Each problem is designed around real business domains and written to look like code you might actually find in production.
For example, bundler configuration is something you’ll encounter in almost any modern project. Or working with markdown, which is everywhere — documentation, wikis, blogs (including this very article).
Learning with realistic examples makes it easier to transfer skills directly to your daily work.
The Right Amount of Theory
Every Debugit task comes with a detailed explanation. It helps you make sense of the debugging process and understand why JavaScript behaves the way it does. You’ll also find tips on avoiding similar mistakes in the future. If you get stuck, the solution is there — because in real life, we also ask teammates for help.
Debugit is built to make practice feel closer to real work and more rewarding than theory alone. By fixing real bugs, you build habits and intuition directly applicable to your job.
