A non-exhaustive list of WebGL and WebGPU frameworks and libraries. It is mostly for learning purposes as some of the libraries listed are wip/outdated/not maintained anymore.

Engines and libraries


three.js: JavaScript 3D library
stack.gl: an open software ecosystem for WebGL, built on top of browserify and npm.
PixiJS: Super fast HTML 5 2D rendering engine that uses webGL with canvas fallback
Pex: Pex is a javascript 3d library / engine allowing for seamless development between Plask and WebGL in the browser.
Babylon.js: a complete JavaScript framework for building 3D games with HTML 5 and WebGL
Filament: Filament is a real-time physically based rendering engine for Android, iOS, Windows, Linux, macOS and WASM/WebGL
ClayGL: A WebGL graphic library

    async/await is just the do-notation of the Promise monad

CertSimple just wrote a blog post arguing ES2017's async/await was the best thing to happen with JavaScript. I wholeheartedly agree.
In short, one of the (few?) good things about JavaScript used to be how well it handled asynchronous requests. This was mostly thanks to its Scheme-inherited implementation of functions and closures. That, though, was also one of its worst faults, because it led to the "callback hell", an seemingly unavoidable pattern that made highly asynchronous JS code almost unreadable. Many solutions attempted to solve that, but most failed. Promises almost did it, but failed too. Finally, async/await is here and, combined with Promises, it solves the problem for good. On this post, I'll explain why that is the case and trace a link between promises, async/await, the do-notation and monads.
First, let's illustrate the 3 styles by implementing

  
## fxn.js
// Replace this:
for (const value of myArray) {
	console.log(value)
}
// with:
forEach(value => console.log(value), myArray)

const double = x => x * 2
map(double, [1, 2, 3])
