React Fibre Deep Dive

Understand how react fibre works

We know that ReactDOM builds the DOM tree under the hood and renders the application on the screen. But how does React actually build the DOM tree? And how does it update the tree when the app’s state changes?

In this post, we’ll learn what React Fiber is and how React built the DOM tree until React v15.0.0, the pitfalls of that model, and how the new model from React v16.0.0 to the current version solves these problems.
