📊 By the numbers
What's actually on the platform
These numbers come from the codebase at build time — not marketing copy. Lessons, projects, paths, badges, and challenges are real counts of files shipped. If the site says 1,300+ lessons, it's 1,300+ actual lessons, not 1,300+ fake claims.

Lesson types
Different lesson formats keep the rhythm varied. Quiz lessons (conceptual) sit next to write (active coding), predict (output guessing), and mission (capstone projects).

We deliberately don't publish "students learning" or "jobs landed" counters here — those would need fake numbers to be impressive. When we have real ones from real users, they'll live on /success-stories.
