How to get the returned value in ionic 2?

I have 2 functions and I'm trying to get the returned value of other function to continue but the returned value always undefined.

This is my code to return values.

export class HomePage {

  variables={
    a:1,
    b:2,
    c:3,
  }

  constructor(public navCtrl: NavController) {
     this.function1();
  }

  function1(){
     if(function2()){
        alert("true");
     }else{
        alert("false");
     }
  }

  function2(){
     if(this.variables.a + this.variables.b >= this.variables.c){
        return true;
     }else{
        return false;
     }
  }
}

Since you're declaring both functions as part of the component, you need to use the this keyword to execute them:

 function1(){
     if(this.function2()){ // <--- like this!
        alert("true");
     }else{
        alert("false");
     }
  }
