The examples in this article describe how JavaScript uses the constructor pattern and the prototype pattern in combination. Share it with everyone for your reference. The details are as follows:
function testPrototype2(){ function Person3(name, age, job){ this.name=name; this.age=age; this.job=job; this.friends =["shelb", "court"]; } Person3.prototype = { constructor:Person3, sayName:function(){ alert(this.name); } } var person1 = new Person3("jack",10,"it"); var person2 = new Person3("karry",1,"woker"); person1.friends.push("tom"); console.info(person1.friends); console.info(person2.friends); console.info(person1.friends==person2.friends); console.info(person1.sayName == person2.sayName); }
I hope this article will be helpful to everyone’s JavaScript programming design.
