A minimal starter set

If you want a small, powerful toolkit:

• Main course: freeCodeCamp or The Odin Project
• Reference: MDN Web Docs
• Practice: Exercism or Codewars (+ LeetCode/NeetCode if you’re prepping for interviews)
• Projects: Frontend Mentor + App Ideas (GitHub)

If you tell me your target (web dev, Python, data/ML, backend, interviews) and current level, I can narrow this to a “top 3 for you” list and a simple learning plan.
