I’ve been learning functional programming for quite some time and like the programming paradigm. But, it can be difficult sometimes. Some libraries like lodash.js can be easy to start learning, but others like bilby.js require that you understand more of the functional approach. So, here are some videos that have helped me understand bilby.js better.
This one gives a quick overview. Note that Maybe (Haskell) is similar to Option (Scala)
This video helped you learn about applicatitves, functors, etc.
This helped me learn about design patterns used in the library bilby.js
