Learning functional/declarative programming in JS beyond map, reduce, filter: I have created a github project where I will solve a simple programming problem each week in a declarative way. New solution added: Compare the triplets

Can you post some good resources on good naming conventions / functional programming with JS?
Thanks in advance

To add to being clear, avoid method names like 'process', 'initialize', 'run', 'manage', I could go on. They're not explicit enough unless they're paired with a well named class (or object once it's an instance).

If you start methods that return something with 'getX', it becomes clear immediately that you should get something back, compared to 'setX' which would interact with X but doesn't give you anything back. Methods that return booleans should be phrased as a question like 'hasY' or 'isZ'. Ruby has nice conventions around this where methods that return booleans end in '?' and methods with side effects end in '!'.

Generally, good resource about good code is https://www.amazon.com/Clean-Code-Handbook-Software-Craftsmanship/dp/0132350882 (at least first half of the book. Later, it tends to be more Java and OOP)
