__proto__、prototype、constructor 之间的关系

引用 李松峰 老师的PPT

 

 1 var Person = function(living, age, gender) {
 2   this.living = living;
 3   this.age = age;
 4   this.gender = gender;  
 5 };
 6 
 7 Person.prototype.getGender = function(){
 8   return this.gender;
 9 };
10 
11 var child = new Person(true, 25, 'male');
12 
13 console.log (child.getGender()); // male
14 console.log (child.__proto__ === Person.prototype);//true
15 console.log (child.constructor === Person);//true
