Standardized Ladder of Functional Programming

The LambdaConf Ladder of Functional Programming (LOFP) is a standardized progression of different concepts and skills that developers must master on their journey to becoming expert-level functional programmers. LOFP can be used to rank workshops, talks, presentations, books, and courseware, so that aspiring functional programmers have a better understanding of what material is appropriate for them given their current experience.

Advanced React by React Training

Personal notes while working through Advanced React: https://courses.reacttraining.com/p/advanced-react

Granted this is a contrived example, but it's still something I took notice to: in those "Advanced React" videos I've been watching, Ryan Florence codes very slowly, and does not make one quick change and jump back to the browser to see what changed.

He stops and thinks. He asks himself (or the viewer) questions. He wonders what
