BybeCode: learn to code

Learn to code by writing it.

From the first lesson you write code and run it. Python really runs inside your phone, with no internet and no server: this is not a simulator comparing your text against the right answer.

A CAREER, NOT A COURSE

You start as a Student and reach Principal through eight ranks. Getting past some of them takes more than XP: there is a technical interview to pass, like in real life. That is what BybeCode has and a course does not.

GETTING IT WRONG COSTS NOTHING

No lives, no hearts, no starting over. A wrong answer gives less XP and the question comes back at the end of the lesson, which is when it actually sticks.

YOUR STREAK SURVIVES A BAD DAY

Uptime counts the days you coded. Every week you earn a hotfix: it covers the day you could not, and your streak goes on. Nobody should lose three months of work to the flu.

WHAT IS INSIDE

• Python and JavaScript, over twenty units each • Over 2,500 exercises where you write, reorder and hunt the bug • Over 280 algorithm challenges, from O(1) to O(2ⁿ) • 12 technical interviews, from Junior to Principal • A project at the end of every unit

NUBE, WHO EXPLAINS

When you get it wrong, Nube does not say "incorrect": it says which line the bug was on and why. Staring at an error you do not understand is what makes people quit.
