Functional programming and monads open new doors.

Even if you're programming javascript, ruby and python - you will be able to write better code and take all those patterns and incorporate them into things.

What needs to be known is that this involves a deeper level of thinking.

To be blunt, only the very best programmers can truly understand functional programming. Once they do, they can take any programming language and pretty much make it bug free, reuseable and readable like english.

Functional programming is for the top 1% of programmers / highest IQ's in society. So this blog may not be useful and perhaps seen as ignorant by non FP.
