Immutable Data 就是一旦创建,就不能再被更改的数据。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...

Redux is an open-source JavaScript predictable state container. Redux is typically used to create user interfaces, in conjunction with libraries such as React or Angular. What is Immutable.js? Immutable.js is a library designed for the creation of immutable collections of data. It is commonly us...
A little while ago I briefly talked about my latest blog rewrite and promised to go more in-depth on specific things I learned. Today I'm going to talk about immutable data structures in JavaScript, specifically two libraries immutable.js and seamless-immutable. There are other libraries, but...

If you're looking for his unsupported package, see this repository.LicenseImmutable.js is MIT-licensed.About Immutable persistent data collections for Javascript which increase...
Immutable.js provides several conversion methods to migrate one structure to another. Each Immutable.js class contains a prefixed "to" method like Map.toList(), Map.toSet(), etc. Converting these types sometimes results in a loss of data, as we will see when converting from Map to List....
Keep in mind, when using JS objects to construct Immutable Maps, that JavaScript Object properties are always strings, even if written in a quote-less shorthand, while Immutable Maps accept keys of any type.const { fromJS } = require('immutable'); const obj = { 1: 'one' }; console.lo...
不可变数据 (Immutable Data )就是一旦创建,就不能再被更改的数据。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。Immutable 实现的原理是持久化数据结构( Persistent Data Structure),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...
