> React hooks are an interesting and tricky thing to put in a box, because they’re almost monads, almost thunks, almost algebraic effects. The interplay with fibers and components makes them hard to pin down, but they are much closer to functional than any other paradigm. They're almost classes (/objects). The implementation is what it'd look like if you wanted to make a weird half-assed OO... thing. Property and method declarations, getting attached (ultimately) to an object. But it's FIFO access/calling, rather than using named properties and methods w/ a lookup step. And the declaration syntax is bizarre and hard to read. And they're slower than regular JS OO (because they add an extra layer of JS on top of it).
