Functional Programming

Practical Functional Javascript with Ramda

Data flows right-to-left in Ramda

R.map(R.add(1), [1,2,3]); // 2,3,4

Allows us to use shorthand to easily access attributes on an item

return getItems()
  .then(R.pluck('attr'));

Pipe comes in handy when you want to compose a series of functions together but want to organize them logically in left-to-right order

var getCostWithTax = R.pipe(
  R.prop('cost'), // get cost
  R.multiply(1 + TAX_RATE) // calculate tax
);

It doesn't look like pPipe made it into the current version of ramda...

Dr. Boolean's Mostly Adequate Guide

A pretty solid introduction to functional programming concepts. I've already read a bit of the first couple chapters but could use a refresher on Currying, Pointfree, and Composition.
