Treehouse JavaScript Framework

http://github.com/markevans/treehouse
一个名为Treehouse的开源库，用JavaScript编写，与React一起工作.

它是一个固执己见的框架，用于处理单页JavaScript应用程序中的状态. 它为更新和查询单个不可变状态树提供了游标和其他工具.

它的作用域与Redux相似，可以看作是Redux的替代品.

由于JavaScript框架市场已经饱和，它没有被公开，因为像Redux这样的工具得到了很好的支持和充分的支持. 然而，事实上，比起Redux，我更喜欢Treehouse的方法.

Details for its use are here: http://github.com/markevans/treehouse.
