What is the advantage of this plugin over this.state()?

Question

JavaScript

I came across such a plugin
I was interested in this key feature

The render method is never executed immediately. Triggered renders are collected and executed asynchronously in one batch.

What is the benefit of asynchronous render()? And if it's better than react suggests, why didn't they implement it themselves?

Answer 1

This plugin uses a native observable which is not yet available in all browsers as far as I know. That is, it calls the render() or forceUpdate() function when the same observable says.
Look, it's pretty simple: easyState.js
Google: js native observable
