Fun with an Object and Four Timers

This project creates an object prototype using the setInterval function, and then creates four instances of the object with different intervals running concurrently.

The object prototype:

function testObj(name,mcount,interval){
  this.Name=name;
  this.Mcount=mcount;
  this.Count=0;
  this.Interval=interval;
  this.ID=0;

//Methods
  this.doCount=function(){
   this.Count++;
   if(this.Count <= this.Mcount){
    console.log(this.Name," ",this.Count);
   }else{
    clearInterval(this.ID);
    console.log(this.Name," Finished");
   }//endif
  },//end doCount

}//end testObj

Two functions used to test the object:

// Test the testObj methods 
function Test(name,mcount, interval){
 // create an instance of testObj
var Y=new testObj(name,mcount,interval);
Y.ID=setInterval(function(){Y.doCount();­},Y.Interval);
 console.log(Y.Name," started");
  console.log("Test End");
}//end Test

function Test1(){
 // create an instance of testObj
var Y=new testObj("Third",10,1500);
Y.ID=setInterval(function(){Y.doCount();­},Y.Interval);
console.log(Y.Name," started");
console.log("Test End");

var Y1=new testObj("Fourth",10,2000);
Y1.ID=setInterval(function(){Y1.doCount(­);},Y1.Interval);
console.log(Y1.Name," started");
console.log("Test End");
}//end Test

The code that calls the functions:

console.log(process.memory());
Test("first",10,500);
console.log(process.memory());
Test("second",10,1000);
console.log(process.memory());
Test1();
console.log(process.memory());
//When Fourth finishes type this into the left side
//  console.log(process.memory()); 
//Compare the Usage at the start, as each task is added and at the end

Some of the output in the left pane of WebIDE:
