Internals of Async / Await in JavaScript

• kal

  2 396 10.0 JavaScript

  A powerful, easy-to-use, and easy-to-read programming language for the future.

It's obsolete now, but before async/await was part of JS proper I worked on a compile-to-JS language that handled this by compiling to callbacks: https://github.com/rzimmerman/kal

It included try/catch support and fancy stuff, like loops. The source may be interesting for anyone interested in compilers: https://github.com/rzimmerman/kal/blob/master/source/generat...

The Kal compiler is written in Kal, but it's supposed to be easy to read. Surprisingly the browser demo still works: http://rzimmerman.github.io/kal/demo.html

• redux-saga

  42 22,501 4.0 JavaScript

  An alternative side effect model for Redux apps

  

The whole article properly the best explanation of generators I have come across. This quote stuck out:

> Generators are a special type of function that can return multiple pieces of data during its execution. Traditional functions can return multiple data by using structures like Arrays and Objects, but Generators return data whenever the caller asks for it, and they pause execution until they are asked to continue to generate and return more data.

Applications of generators? I have only used Redux-Saga[1]. Can't even think of other libraries that use them, but would be interested in learning.
