“The way to create an 'object type', is to use an object constructor function.
Objects of the same type are created by calling the constructor function with the new keyword.”
by W3C School
As the example we mentioned in the last article, there was only one trip.
Now, if we have multiple trips’ score to count, we’ll need a constructor to help us.
function Trip(name,score){ //When it comes to creating a construtor function, usually people use capital letter.
this.name=name; //"this" represents an empty object auto created by the system.
this.score=score;
this.outdoor=function(){
this.score=this.score+10;
};
this.rainyDay=function(){
this.score=this.score-5;
};
this.snacksnBBQ=function(){
this.score=this.score+20;
};
this.napping=function(){
this.score++;
};
this.report=function(){
alert(this.name+":"+this.score)
};
}
var trip1=new Trip("Couple Trip",70); //befor constructor, adding a "new"
trip1.outdoor();
trip1.napping();
trip1.report();
→ The result is 81
var trip2=new Trip("Company Trip",60);
trip2.rainyDay();
trip2.snacksnBBQ();
trip2.report();
→ The result is 75
