npm install flap> :rooster: Guard clauses for JS
-----
flap allows you to cleanly enforce integrity conditions and modifications to the inputs and outputs of functions.
You can also think of it as a generic datal-flow wrapper for functions, with a dash of pattern-matching awesomeness.
* Wraps JS functions and their arguments with guard clauses found in languages such as Elixir and Haskell
* Elegantly modifies and reacts to arguments based on expressions
* Pattern matching against object arguments
* Improves readability of complex conditions by chaining discrete units of logic
* Helps prevent deep nesting and callback hell
* Optionally bind to Function.prototype for maximum sugar
