Demystifying React with Vanilla JS by Fernando Doglio 

React, Vue.js, and all those frameworks that call themselves “reactive” work around the concept of one-way data binding. In other words, they give developers the ability to bind their models to the representation. And on top of that, they let you modify the view automatically when you modify the data, hence the name "one-way data binding".
In this talk, Fernando Doglio talks about how you can reproduce that magic with plain old Vanilla JS.
