资源说明：Functional (-ish) data structures for Javascript (via Coffeescript)
== pazy - Functional (-ish) data structures for Javascript (via Coffeescript[http://jashkenas.github.com/coffee-script/]) The name pazy is a contraction of persistent[http://en.wikipedia.org/wiki/Persistent_data_structure] and lazy[http://en.wikipedia.org/wiki/Lazy_evaluation]. This is my humble attempt at implementing a collection of practical, immutable data structures for use in my Javascript projects. I am using Coffeescript instead of plain Javascript because it provides a clutter-free way of writing code that translates into clean and straightforward Javascript. Currently included are various collection classes inspired by Rich Hickey's persistent hash tries (as found in his Clojure[http://clojure.org] programming language), several data structures described by Chris Okasaki in his PhD thesis, an experimental implementation of arbitrary precision integers based on lazy sequences, a union-find data structure and some useful primitives such as suspend and recur/resolve. The latest addition are finger trees. I am not a specialist in functional programming or data structures, and I am fairly new to Javascript, so more than anything else, this is about me figuring out how these things work. Nonetheless, I am trying to make the code as efficient and robust as possible without sacrificing clarity. A test suite using the fantastic Jasmine[https://jasmine.github.io/] framework is included.
