OT; but can anybody can hint me to a good ressource where to learn more about Promises and how to use them correctly?

I found this pouchdb blog post[1] really helpful when first trying to wrap my head around promise chaining patterns. Highly recommend!

This might sound bonkers at first, but I think I did not really understood promises until I implemented the spec myself (with a lot of studying others' code that is).

It's actually not too time-consuming (I think it took me an afternoon) and there is a test suite covering the entire spec on npm: https://www.npmjs.com/package/promises-aplus-tests so you can just hack away until everything is green.

Check out this guide: https://scotch.io/tutorials/javascript-promises-for-dummies

The pouchdb blog post linked is really good too!
