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. AN AI TUTOR THAT WILL NOT GIVE YOU THE ANSWER Stuck on a challenge? Ask Nube. It looks at your code and your test results and gives you a hint, each one more specific than the last, but never the solution: the point is that you solve it. You can also ask it anything about Python or JavaScript in its chat. IT WORKS WITHOUT AN ACCOUNT You can study without signing up. An account is what keeps your progress from living only on this phone, and it is what you need to talk to the tutor. WHAT IS FREE, AND THE PASS Unit 1 of Python and JavaScript, the first challenges and the Junior interview are free, with no expiry date. The rest opens with the 6-month pass: a single payment that does not renew on its own.
