Youtube Summary
In object-oriented development, we are all familiar with design patterns such as the Strategy pattern and Decorator pattern, and design principles such as SOLID.

The functional programming community has design patterns and principles as well. This talk provides an overview of some common FP patterns, from the basics of partial application and currying all the way to monads and monoids.

This is exactly the resources I've been looking for to advance my understanding of how to accomplish certain things in FP before trying to learn it wholesale.

I have his book Domain Modelling Made Functional as it comes very highly recommended. I haven't gotten to it yet, but I'm even more excited for it now after watching this.

I would highly recommend this talk by Scott Wlaschin https://www.youtube.com/watch?v=srQt1NAHYC0
I agree, F# is hard to learn. It took me a few months of tinkering to be able to express myself in it.

Good entry points: Don Syme - his "F# Code I Love" talk has been recorded a few times: https://www.youtube.com/watch?v=aw2BAxG3bdM. I recommend catching a few versions.

Scott Wlaschin - His talks are also great: https://www.youtube.com/watch?v=srQt1NAHYC0. He also runs https://fsharpforfunandprofit.com/ which is a treasure trove.

And I found Isaac Abraham's book excellent and breezy to read: https://www.manning.com/books/get-programming-with-f-sharp

Now that I'm over the hump, I think F# code is far more readable than other languages I'm well versed in (C++/C#). Probably my favorite thing about F# is the strict top-down dependencies. You can open a project and read it in order, and understand it without having to hop around a bunch.

And since most programs can be written in far fewer lines in F#, code written in it ends up feeling very small and economical.
