+# 函数
+
+###### call,apply,bind
+
+改变this指向，函数被执行时，内部会产生一个this
+
+arguments:伪数组,只有下标，长度，元素是实参的映射
+
+实列：（call apply 两者类似）
+
+```
+function Person(name, age) {
+
+ var { name : '张三' ,age:18}
+
+ console.log(this);
+
+ this.name = name; //obj.name = name;
+

+ return {}
+
+ }
+
+ var obj = {};
+
+Person.call(obj,'张三',18);
+Person.apply(obj, ['张三', 18]);
+Person('张三',18);
+```
+
+实列：bind
+
+```
+ // const module = {
+ // x: 42,
+ // getX: function () {
+ // console.log(this);
+ // return this.x; //window.x
+ // }
+ // };
+
+ // var x = 99;
+ //bind
+ // const unboundGetX = module.getX;
+ // console.log(unboundGetX()); //42
+ // const boundGetX = unboundGetX.bind(module);//函数 调用bind方法，返回一个带this指向的新函数
+ // console.log(boundGetX());
+```
+
+#### 严格模式（'use strict'）
+
+：严格模式:防止意外发生错误时，及时抛出该错误
+
+1.在严格模式下，函数内部不会再意外地生成全局变量，而是抛出异常
+
+2.严格模式要求一个对象内的所有属性名在对象内必须唯一
+
+3.严格模式下会抛出错误，非严格模式会自动转换全局
+
+4.构造函数使用严格模式,必须使用new：
+
+```
+ // function Product(name, price) {
+ // 'use strict'
+ // this.name = name;
+ // this.price = price;
+ // }
+ // new Product('张三',18);
+```
+
+函数命名
+
+ //构造函数:Person()
+
+ //普通函数小驼峰: getNameAge
+
+ //普通变量: personAge perons_age
+
+ //常量:PI

+# 原型链和继承
+
+原型链继承：会将父级上的所有属性和方法统统继承过来（过多地继承没用的属性）
+
+添加属性必须在重写之后否则不会生效
+
+###### 原型链继承
+
+原型链 继承:继承父类的属性和方法
+
+原型链继承：会将父级上的所有属性和方法统统继承过来：过多地继承没用的属性
+
+列如：
+
+```
+function Grand(){}
+function Parent(){}
+Grand.prototype.tskill = '拉二胡';
+var grand = new Grand();
+Parent.prototype = grand;
+var parent = new Parent();
+Parent.prototype.tskill = '弹琴';
+其中如果要添加属性，需要在重写之后
+```
+
+
+
+###### 构造函数继承
+
+例子：
+
+ `function Parent(name,age){`
+
+ `this.name = name;`
+
+ `this.age = age; `
+
+ `}`
+
+
+
+ `function Child(name,age,sex){`
+
+ `Parent.call(this,name,age);`
+
+ `this.sex = sex;`
+
+ `}`
+
+构造函数的属性优先于原型上的属性
+
+
+
+###### 共享原型继承
+
+子级上的修改会影响所处同一原型链上的所有对象
+
+例子：
+
+ `function Parent(){`
+
+ `}`
+
+ `Parent.prototype.name = '爹';`
+
+ `Parent.prototype.age = 40;`
+
+ `function Child(){`
+
+ `}`
+
+Target：指向的构造函数
+
+Origin：源头的构造函数
+
+ `function inherit(Target,Origin){`
+
+ `Target.prototype = Origin.prototype;`
+
+ `}`
+
+ inherit(Child,Parent)
+
+
+
+###### 圣杯模式
+
+例子：
+
+ `function Parent(){`
+
+ `}`
+
+ `Parent.prototype.name = '爹';`
+
+ `Parent.prototype.age = 40;`
+
+ `function Child(){`
+
+ `}`
+
+ `function inherit(Target, Origin) {`
+
+ `function F(){} `//临时构建函数
+
+
+
+ `F.prototype = Origin.prototype;`
+
+
+
+ `Target.prototype = new F();`
+
+
+
+ ``Target.prototype.constructor = Target;`
+
+
+
+
+
+ `Target.prototype.uber = Origin;`
+
+
+
+ `}`
+
+ inherit(Child, Parent);
+
+
+
+这种圣杯模式的本质在于，中间生成了一个对象（构造函数），起到了隔离的作用，今后为child.prototype添加属性时，全部都会加在这个对象里面,所以不会对父级产生影响。而向上查找是沿着_ proto_查找，可以顺利查找到父级的属性，实现继承。
