Curso para aprender el lenguaje de programación JavaScript desde cero y para principiantes. +120 lecciones, 14 horas en vídeo y 220 ejercicios.
A free, Spanish-language JavaScript course built from Twitch livestreams, aimed squarely at total beginners with no prior programming experience. It's vanilla JS fundamentals only — variables through modules, closures, async, basic DOM, regex, and Jest — split into two 12-14 hour video courses with matching code and exercise files per lesson.
Every lesson maps to a timestamped YouTube link plus a corresponding .js file, so you can watch or just skim the code and exercises without sitting through video. Topic coverage for a fundamentals course is unusually complete — it goes past syntax into prototypes, mixins, Proxy, currying, and the event loop, not just the typical variables/loops/functions checklist. The exercises are separated from the teaching code, which pushes you to actually practice instead of reading past it.
Everything is in Spanish, including all video content, README, and comments — a hard wall for the huge chunk of this repo's potential English audience. No package.json testing setup or CI, so the 'Testing' section with Jest is really just one demo file, not something you can run and grade yourself against. Last push was mid-2025 and the course itself dates to a 2022-era livestream format, so any DOM/API examples referencing service specifics could be stale. It's explicitly not project-based — there's nothing here that teaches you to structure or ship an actual application, only isolated language mechanics.
