In a detailed guide, Rodrigo Pombo explains how to build a simplified version of React from scratch, focusing on React 16.8 with hooks. The process involves creating functions like createElement and render, implementing Concurrent Mode, Fibers, and handling reconciliation. The tutorial provides step-by-step instructions on recreating React's core functionalities using vanilla JavaScript. By breaking down the rendering process into smaller units of work and utilizing requestIdleCallback, the tutorial aims to prevent blocking the main thread during rendering. Additionally, it introduces the concept of Fibers as a data structure to organize units of work efficiently. The tutorial emphasizes understanding the inner workings of React by implementing key features gradually. While the tutorial references React's internal mechanisms, it encourages readers to build their own React-like library called Didact.

Every single time I look into them I just can't find a reason why I'd ever want to use them over regular HTML and JavaScript. This is especially true in recent years when so many convenience functions have been added to the languages which you'd only previously find in the likes of jQuery etc.
I've looked at framework comparison sites like ToDoMVC.com and the React code just looks so disgustingly over-engineered.
I just don't get it at all.
Now, it looks like I can do just that, maybe?
