  	this.numbers = [1,2,3];
    this.token = "token";
  }
  
  doSomething(){
  	setTimeout(function doAnotherThing(){
    	this.numbers.forEach(function log(number){
      //Cannot read property 'forEach' of undefined
      		console.log(number);
          console.log(this.token);
      });
    }, 100);
