 intervalID: number;
  value: number=0;

startGame(){
    console.log("gameStarted");
    this.intervalID=window.setInterval(this.currentNumber,2000); 
  }

currentNumber(){
    console.log("in current number");
    console.log(this.value);//**Here i am getting undefined**
    this.value++;
    console.log(this.value);// **here i am getting NaN**
    this.numberGenerated.emit({currentValue:this.value});
  }

When using value in currentNumber, i am getting undefined. As a result any operations done on value leads to NaN

Change : 

 this.intervalID=window.setInterval(this.currentNumber,2000);

To: 

this.intervalID=window.setInterval(() => this.currentNumber(),2000);

As arrow functions preserve this.
