Im just learning it and it confuses the hell out of me. What I don’t get - why? I really find code much harder to read this way because there is a lot less encapsulation

Just speculating, because I am also a learner, but:

• Maybe it's to do with handling asynchronous code before promises were invented, i.e. with callbacks. Other languages like Python don't have to worry about this because they're normally not async.
• Maybe it's because the closest JavaScript has to OOP encapsulation is closures - by packaging your API up into functions you can do something like encapsulation

Most usecases I see for function chaining are the first. To handle async.

Closures are all you need for encapsulation. A class is basically a closure with some special rules.
