In the summer of 2024, I set myself a small personal challenge:
write a simple interpreter from scratch.

Without a grand vision I started this project. Just me, some free time, and the curiosity to try something new.

At first, Kocha Lang wasn’t even Kocha Lang. The original goal was to build a bare-bones interpreter — a learning project to stretch my skills. But somewhere along the way, I decided to make the process more fun. I thought “What if I created a programming language entirely in Uzbek street slang?”

Shared it

Once I had the basic functionality working, I decided to share it with people.

So I wrote some documentations, created a syntax highlight vs-code extention and released the project in Tasdev community

Something that started as a personal joke quickly became a talked-about project in local developer communities. To be clear, most people treated it as a joke — not as some kind of technical masterpiece (as they should).

Impressions

By the time I’m writing this post, the GitHub repository has gained 50+ stars. Not bad for a slang-based language that nobody asked for.

What really mattered to me, though, was what I learned in the process:

• How interpreters work under the hood
• How community feedback (even playful) can make a project more enjoyable
• That with time and dedication, you can build anything

Current state

Kocha Lang still has its fair share of limitations and bugs. I fix them from time to time, and I plan to keep it alive as long as it brings joy (or at least a laugh) to someone out there.

To everyone who supported this project, shared it on social media, or even just wrote a single line of Kocha Lang code — thank you. You made this fun little idea feel like something worth doing.
