E.g. - Our current big project at work uses a lot of Javascript. My coworkers are primarily die-hard Java developers (I know Java, but I don't "live" there...). As Douglas Crockford said in a presentation "[those people] will go to their graves, never knowing how miserable they were".

Rather than writing a bunch of classes with one meaningful method ("Executioner", anyone?), I would rather use FP / higher order functions techniques (e.g. - partial function application, such as in Ramda.js). Also, the idea of anything approaching metaprogramming is very scary to them, rather than pasting in many copies of the same stuff with minor variations. Perhaps it's ("custom") abstraction in general that is scary, since so little is documented in most industry standard practice code.

At what point do you ask your coworkers to realize that the eighties are over, and [static] OOP is not the one true hammer of sole best practice any more???
