Reactivity From Scratch

In this 7-day course, you'll learn how to build Vue 3's reactivity system from scratch:

• Day 1: Build a basic reactivity system inspired by Vue 2, including ref() and dependency tracking
• Day 2: Implement reactive() using Vue 3's powerful proxy-based system for deep reactivity
• Day 3: Create watchEffect() with advanced features like scheduling, cleanup, and manual stopping
• Day 4: Develop computed refs for creating derived reactive values
• Day 5: Master ref manipulation with isRef(), unref(), and toRefs()
• Day 6: Implement readonly and shallow reactivity for fine-grained control
• Day 7: Build a reactive store, combining all concepts into a powerful state management solution

By the end of the course, you'll have:

• A deep understanding of Vue's reactivity system
• Implemented core functions like ref(), reactive(), computed(), and watchEffect()
• Created utility functions like isRef(), unref(), and toRefs()
• Built a simple but powerful reactive store similar to Pinia
• Hands-on experience with proxy-based reactivity, dependency tracking, and effect scheduling

Whether you're a Vue beginner or an experienced developer, this course will give you invaluable insights into the inner workings of Vue's reactivity system.
