讲到这边,就可以来公佈第二题的解答了,答案是:A. 会,在这情况下 PureComponent 会比 Component 有效率,因为继承了 PureComponent 之后,只要 props 跟 state 没变,就不会执行 render function,也不会执行 virtual DOM diff,节省了许多开销。 shallowEqual 与 Immutable data structures 你刚开始在学 React 的时候,...

网络不可变数据结构 网络释义 1. 不可变数据结构 另外,使用不可变数据结构(immutable data structures),比如字符串,元组,强调了一种无副作用的编程方式。采用这种编程方 … hgoldfish.com|基于4个网页 例句
Duplicates of immutable data objects are identified and deduplicated. This is performed by performing a bottom up deduplication, such that objects in hierarchically lower levels of a data structure are deduplicated first. Deduplication identifies duplicates of a particular object through value equality ...

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...
Immutable.js provides many Persistent Immutable data structures including:List,Stack,Map,OrderedMap,Set,OrderedSetandRecord. These data structures are highly efficient on modern JavaScript VMs by using structural sharing viahash maps triesandvector triesas popularized by Clojure and Scala, minimizing the...
Immutable JS data structures which are backwards-compatible with normal Arrays and Objects. Use them in for loops, pass them to functions expecting vanilla JavaScript data structures, etc. var array = Immutable(["totally", "immutable", {hammer: "Can’t Touch This"}]); array[1] = "I'm ...
ImmutableJS最大的两个特性就是:immutable data structures(持久性数据结构)与structural sharing(结构共享),持久性数据结构保证数据一旦创建就不能修改,使用旧数据创建新数据时,旧数据也不会改变,不会像原生js那样新数据的操作会影响旧数据。而结构共享是指没有改变的数据共用一个引用,这样既减少了深拷贝的性能消耗,...
