JavaScript: Advance async patterns

One of the best video tutorials about JavaScript async patterns is from Kyle Simpson. I watched this video about three years ago and it's still relevant today.

I am writing this post for myself to refer through the async concepts which are vital in writing JS applications.

Without further ado,

In summary he talks about,

1. Callbacks
2. Promises
3. async await
4. Observables (RxJS)
5. Communicating sequential processes (CSP)

All of which can achieve the same results (concurrent async calls) but he shows how you can improve your code by adapting advance async patterns.

I thought it's good one to remember even if it out-dates in the future.
