对 Immutable 对象的任何修改或添加删除操作都会返回一个新的 Immutable 对象。主要原理是采用了 Persistent Data Structure(持久化数据结构),就是当每次修改后我们都会得到一个新的版本,且旧版本可以完好保留,也就是使用旧数据创建新数据时,要保证旧数据同时可用且不变。同时为了避免 deepCopy 把所有节点都复制一遍带来...

JavaScript/Elm/Python/Clojure/Java/... React 通过 Immutable 加快比对速度。 文件系统的 COW 机制,在复制数据到指定区间的时候,会先将旧的数据拷贝一份,避免意外导致的数据丢失。 二 实现方式 实现Immutable 的方式有很多,下面介绍几种常见的方式。
Immutabledata cannot be changed once created .Persistentdata presents a mutativeAPIwhich does not update the data in-place, but instead always yields new updated data. Immutable.js provides many Persistent Immutable data structures including:List,Stack,Map,OrderedMap,Set,OrderedSetandRecord. These data...
