+#### 创建对象
+
+```js
+//字面量
+var obj = {
+	name = 'JOJO';
+	action(){
+		ola = '欧拉';
+	}
+}
+//构造函数
+function func(name){

+var par = 'FF';
+```
+
+#### 对象解构
+
+```js
+//简单直接
+let{name} = obj;
+console.log(name);
+//取别名	
+let{name:personName} = obj
+console.log(parsonName);
+//先声明，后赋值	
+let name;
+({name} = obj);	-- 必须要加小括号
+//嵌套解构 --键值对的方式
+let{action:{ola}} = obj
