Week 1: fundamentals (closures, this, call/apply/bind). Week 2: async (event loop, promises, async/await). Week 3: patterns (currying, debounce, throttle). Week 4: DOM (events, bubbling, delegation, CORS). Week 5: prototypes, polyfills. Week 6: practice and mock interviews. 6 weeks of consistent study.

4-6 weeks of consistent study (1-2 hours per day). This gives enough time to understand each concept deeply, implement from scratch, and practice. Cramming in 1-2 days is not enough for deep JS understanding.
