May 17Highly Functional
by in Representative Line on 2017-06-19For a brief period of time, say, about 3–4 years ago, if you wanted to sound really smart, you’d bring up “functional programming”. Name-dropping LISP or even better, Haskell during an interview marked you as a cut above the hoi polloi. Even I, surly and too smart for this, fell into the trap of calling JavaScript “LISP with curly braces”, just because it had closures.
Still, functional programming features have percolated through other languages because they work. They’re another tool for the job, and like any tool, when used by the inexpert, someone might lose a finger. Or perhaps someone should lose a finger, if only as a warning to others.
