AI learning answer
How do I learn Claude Code for a real codebase?
Short answer from Learnetto's Best Claude Code courses and tutorials guide.
Short answer
Start with a small real task, let Claude Code inspect the repo, ask for a plan, review the diff, and run tests. That teaches the workflow better than a toy app demo.
Context from the full guide
Start with the DeepLearning.AI Claude Code course or Peter Yang's beginner tutorial, then use Anthropic docs and real-world feature-build walkthroughs to learn planning, editing, testing, and review habits.
