Detailed answers to JavaScript simulated overloading and rewriting of toString method

Now I will explain in detail the javascript simulation overloading and the rewriting of the toString method. Please see the code below for details.

/***重载模拟***/
function _person(){
var args=arguments;
if(typeof args[0]=="object"&&args[0]){
if(args[0].name){
this.name=args[0].name;
}
if(args[0].age){
this.age=args[0].age;
}
}else{
if(args[0]){
this.name=args[0];
}
if(args[1]){
this.age=args[1];
}
}
}

//toString方法的重写
_person.prototype.toString=function(){
return 'name='+this.name+",age="+this.age;
}

//////创建对象
var stu1=new _person("赵四","23");
stu1.toString();

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
