__proto__、prototype、constructor 之间的关系

引用 李松峰 老师的PPT

 

var Person = function(living, age, gender) {
  this.living = living;
  this.age = age;
  this.gender = gender;  
};

Person.prototype.getGender = function(){
  return this.gender;
};

var child = new Person(true, 25, 'male');

console.log (child.getGender()); // male
console.log (child.__proto__ === Person.prototype);//true
console.log (child.constructor === Person);//true
