Hey!

I recently got an email from Ritvik.

He was so inspired by my free "Reactivity From Scratch" mini course that he decided to give this awesome talk on how reactivity works in Vue.

So go watch it and leave some nice comments!

If you're interested in what inspired Ritvik so much, here are some more details on my free "Reactivity From Scratch" mini-course.

We build a Composition API-inspired reactivity system from the ground up.

In it, you will learn to build:

By the end you'll have deep knowledge on:

It's structured as a 7-day email course, so it's easy to keep up with a hectic schedule:

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

Oh, and did I mention that this course is completely FREE?

Whether you're a beginner or an expert at Vue, you'll learn something valuable in this course.
