How to Use This Roadmap
1.Work through phases in order — each builds on the previous
2.Complete the labs section for each phase before moving on
3.Build a project after each phase to cement learning
4.Use the interview section to test understanding regularly
5.Track progress: revisit earlier sections as concepts compound
