Codenjoy

Welcome to Codenjoy!

In Japan, a dojo is a place for trainings, competitions, and attestations in martial arts like aikido, judo, or jujitsu. Figuratively speaking, it is a place where we learn self-discipline, exchange knowledge, and help each other to become better. Engineers decided to borrow the term dojo for programming — we express ourselves through code, which is a craft requiring a place to master new skills. Inspiring, is it not?

So developers get together and start doing ‘katas’ — basic tasks that are repeated to improve their mastery of engineering. In martial arts, a kata is a series of movements against an imaginary opponent. Coding Dojo has various forms, like Codenjoy — coding for fun. Participants create bots that compete in real time in basic games like Tetris, Battlecity, Snake, Sudoku, Minesweeper, Moebius, etc. There are about 30 games in Codenjoy.

My name is Oleksandr Baglai and I started as an engineer on a project in another company. In my free time I helped colleagues learn new technologies and conducted trainings for them. I met software architect Sergii Zelenin while working on a training on test-driven development, and later we heard about Coding Dojo when Sergii was invited to a conference demonstrate a kata with engineer Johannes Brodwall. There they used a different language, so Sergii and I decided to start our own dojo.

We named our version Codenjoy (Code + Enjoy). It was an interesting format, and we shared it everywhere we were invited. Later, the Codenjoy community divided into ‘senseis’, or organizers, programmers who write code, and contributors who add their own games. Participants get feedback based on the game results. Think your development methodology is great? Let’s try it in a tournament. That’s how I stopped telling people how TDD is faster.
