docs: make some notes for immutable.js and moreartyjs

2017:08/30.md

+# moreartyjs
+
+管理（state：结合 immutable ）层
+
+
+1. 向子组件传递：
+
+```
+// pass to sub components
+var binding = this.getDefaultBinding();
+
+<Header binding={ binding } />
+```
+
+2. retrieved: `getDefaultBinding` method 
+
+```
+
+this.getDefaultBinding().update('items', function (todos) {
+	// do sth update here
+})
+```
+
+3. dom 与 callback
+
+```
+<Morearty.DOM.input id='new-todo' // // requestAnimationFrame-friendly wrapper around input
+    ref='newTodo'
+    placeholder='What needs to be done?'
+    onKeyDown={ Morearty.Callback.onEnter(this.onAddTodo) } />
+```
+
+
+# immutable
+
+包括 List, Stack, Map, OrderedMap, Set, OrderedSet 和 Record 以及一系列方法。
+
+常用的有 List、Map 和 Set
+
+```
+const map = Immutable.map({
+	a: 1,
+	b: 2,
+	c: 3
+});
+
+const mapNew = map.set('b', 50);	// note: return totally new object
+```
+
+```
+const list = Immutable.list([1,2]);
+const listNew = list.push(3);
+```
+等等
+
+1. Map 类似 key/value object
+
+```
+const map = Immutable.Map({ a: 1 });
+```
+
+
+2. List 类似一般的 Array
+
+```
+const arr = Immutable.List([1, 2, 3]);
+```
+
+3. Set 没有顺序但不能重复的 Array
+
+```
+const set = Immutable.Set([1, 2, 3]);
+```
+4. tip:  Structural Sharing， 树中一个节点变化，不会影响其他节点
+
+```
+const obj = {
+ count: 1,
+ list: [1, 2, 3, 4, 5]
+}
+var map1 = Immutable.fromJS(obj);
+var map2 = map1.set('count', 4);
+
+console.log(map1.list === map2.list); // true
+
+```
+
+
+5. 常用 API
+
+```
+fromJS(); // js 2 immutable
+toJS(); 	// immutable 2 js
+is(); // 比较的是 两个对象的 hashcode 和 valueOf
+has() hasIn;  // if key in, 加 In：深层
+includes();		// if value in
+```
