Being a (primarily) back-end developer, my use of Javascript has been fairly limited. Mostly using jQuery and some basic raw Javascript in the olden-days for frontend validation, basic animation and alerts etc.

I've been writing a project in Quasar https://quasar.dev/ and delving further into the mysteries of async programming.

I was struggling to understand some documentation I found online. After some digging, it turns out that through various versions of ECMAScript, the concept of asynchronous programming has evolved and changed, giving you multiple ways of doing things with callbacks, promises and async/await.

I found this video on Youtube https://www.youtube.com/watch?v=PoRJizFvM7s which although only 24 minutes long gives a fantastic introduction to how each iteration of callbacks/promises/async/await has been developed, how they work and how to code against them.

It gives and intro with examples and that was all I need to get it straight in my head and make some real progress. It's a must-watch for anyone starting to get involved with Javascript other than simple libraries like jQuery.
