Topic:Node.js
Answer:
One language (JS) for the whole stack — easier FE↔BE switching, most popular in PL startups, fastest start. Python/Java are separate courses.
Choosing Node.js for backend in the Fullstack course has two key reasons. - First — pedagogical: one language (JavaScript) for the whole stack lets the student grasp concepts faster (you do not learn two syntaxes at once) - Second — market: Node.js dominates Polish startups, scale-ups (Booksy, Allegro, Vacation Tracker), and international product companies - Express is the standard for junior Node.js positions - For people preferring Python, Mate offers a separate Python developer course (650h, focus Django/FastAPI) - For Java — a Java developer course (650h, Spring Boot) After Fullstack you can add Python/Java in 2–3 months if a specific job requires it. Fullstack gives you a versatile web developer mindset (source: Mate academy data 2026).
