What I've done today

Generators are functions which can be exited and later re-entered. Their context (variable bindings) will be saved across re-entrances.

Generators in JavaScript -- especially when combined with Promises -- are a very powerful tool for asynchronous programming

I continued with my JS course; the chapter is about generator functions. I did the introduction but do not really see how this would work with a "real world example".

Luckily the DIY programming lesson is coming up which hopefully clearifies that.

What I'm planning to do next

I'll do the hands on and use generator functions and promises to do API calls.
