FPSK | The Functional Programmer's Starter Kit
FPSK really helped me rethink, how I approach programming and code composition.
It taught me alot more than just functional, its a different way of thinking. Definitely worth a read!
Definitely not as difficult or as complicated as it seems. FPSK does a great job breaking it down.
I. Functional Purity and Composition
II. Immutability and Data Structure
III. Promises and More
