You likely use it every day at work.
This makes it possible to practice and apply your acquired knowledge each day on real world programs rather than pet projects on nights and weekends in an esoteric FP language.
We don't have to learn everything up front to start writing programs.
In a pure functional language, you cannot log a variable or read a DOM node without using monads. Here we can cheat a little as we learn to purify our codebase. It's also easier to get started in this language since it's mixed paradigm and you can fall back on your current practices while there are gaps in your knowledge.
The language is fully capable of writing top notch functional code.
bind all over the place lest
this change out from under us, we don't have classes (yet), we have various work arounds for the quirky behavior when the
new keyword is forgotten, private members are only available via closures. To a lot of us, FP feels more natural anyways.
