A "choose your own adventure" story
JavaScript is has both object-oriented and functional heritage, thanks to its two parents: Scheme and Self.
It provides first class functions and makes it simple to compose these function objects into bundles of awesome. Even though I'm an OO "true believer" at heart, I find myself composing my code using functional concepts, and use the OO approach where there's a clear benefit or where I feel that it's the best way to communicate the interface.
Object-oriented software design is by no means the only way to do software design, but it's been an immensely successful model for a very long time now, and provides a clear and well-understood mental model for thinking and communicating about software. Lots of good ideas like encapsulation, delegation, traits and composition fit well into OO design.
Functional programming gets a bad wrap about being too hard for mere mortals to comprehend. This is nonsense. The concepts are actually quite simple to grasp.
The jargon is the hardest part. A lot of that vocabulary comes from a specialized field of mathematical study called category theory (with a liberal sprinkling of type theory and abstract algebra). This sounds a lot scarier than it is. You can do this!
All examples using ES6 syntax. wrap (foo) => bar
means:
function wrap (foo) {
