+## 1.获取属性的值
+
+.
+
+[  ]
+
+相同点：获取属性的值
+
+不同点：
+
+1. [  ] 可以获取变量为字符串的内容，.  不可以
+
+    ```javascript
+        var  str3 = {name:'tuttu',number:'23'}
+        var key = 'name'
+        console.log(str3[key])   tuttu
+        console.log(str3.key)   undefined
+    ```
+
+2. [  ] 可以用纯数字作为属性名，.不可以
+
+    ```javascript
+          var  str3 = {name:'tuttu',3:'23'}
+            var key = 'name'
+           console.log(str3[3])    23
+            console.log(str3.3)    Uncaught SyntaxError: missing ) after argument list
+    ```
+
+普通常量赋值的时候可以用 . 其他可以用[  ]
+
+## 2.对象解构
+
+```javascript
+const hero = {
+    name:'huhu',
+    age:15
+}
+const{name,age} = hero;
+name;
+ageg
+
+//	解构赋值不一定需要与对象的属性匹配。赋值的时候可以忽略某些属性，而如果引用的属性不存在，则为undefined。此时可以在解构的同时定义默认值
+
+let {name, job} = person  //此时没有job属性
+let {nam, job='student'} //设定默认值
