⚠️ Disclaimer

The roadmap above is tentative and evolving.
The technology ecosystem changes rapidly — new frameworks emerge, tools update weekly, and best practices shift with every major release. While this roadmap represents a comprehensive snapshot of the current full stack JavaScript landscape, learners should treat it as a living guide, not a fixed syllabus.

We strongly recommend revisiting this roadmap every few months to track changes, explore new tools, and update your learning plan. The key to long-term success in web development is continuous adaptation, curiosity, and lifelong learning.
