There is no single “correct” order, but these paths reduce rework.
Web developer path
- HTML → CSS → JavaScript
- Optional: TypeScript → React or Vue
- Backend: PHP, Python, or Node.js + SQL
Data & ML path
- Python → Data Science → Pandas / NumPy
- Read AI literacy before Generative AI
Everyone should cover
- Git and Tools early in your journey.
- Cybersecurity before shipping real user data.
Self-check
- Which path matches your goal (web, data, mobile, ops)?
- What prerequisite track will you open next and why?
Interview prep
- Interview angle: how do you pick what to learn next?
Say you prioritize by shipping goal (e.g. web UI → HTML/CSS/JS) and team stack, not buzzwords. You balance breadth with depth on one path until you can ship a small project.
- Why is SQL often recommended even for non-DB engineers?
Most products sit on relational data; reading and reasoning about tables and joins is universal—even if someone else owns the schema.
