Fork of the source code examples from the book Functional JavaScript.

We're adding literate coffeescript variants of examples as we work through the text.

• Introducing Functional CoffeeScript
• First-Class Functions and Applicative Programming
• Variable Scope and Closures
• Higher Order Functions
• Function Building Functions
• Recursion
• Purity, Immutability, and Policies for Change
• Flow-Based Programming
• Programming Without Class

Reference

• errata

• js arrays - MDN quick ref for native javascript array objects

• underscore - handy doc site

• underscore-contrib - various underscore extensions. The library currently contains a number of related capabilities, aggregated into the following files:

  • array.builders - to build arrays
  • array.selectors - to take things from arrays
  • collections.walk - to walk and transform nested JavaScript objects
  • function.arity - to manipulate and fix function argument arity
  • function.combinators - to combine to make new functions
  • function.iterators - to lazily produce, manipulate and consume sequence iterators
  • function.predicates - that return true or false based on some criteria
  • object.builders - to build JavaScript objects
  • object.selectors - to pick things from JavaScript objects
  • util.existential - functions that check for the existence or truthiness of JavaScript data types
  • util.operators - functions that wrap common (or missing) JavaScript operators
  • util.strings - to work with strings
  • util.trampolines - to facilitate calling functions recursively without blowing the stack
