Solution for the last Challenge in Functions

Question

Hello everyone, I just would like to get your guys opinions on my solution for the last challenge (number 2) for Functions. I figured it out this way before finding out that it was to give out an error anyways but i think i used my skills to come up with a way that still produces errors with an alert box.


function getRandomNumber( lower, upper ) {
    return Math.floor(Math.random() * (upper - lower + 1)) + lower; 
    if(isNaN(upper)||isNaN(lower)){
       throw new Error ("Error with the number");
    }else{
      return alert(getRandomNumber);
  }
  }
  alert( getRandomNumber( 'nine', 24 ) );
  alert( getRandomNumber( 1, 100 ) );
  alert( getRandomNumber( 200, 'five hundred' ) );
  alert( getRandomNumber( 1000, 20000 ) );
  alert( getRandomNumber( 50, 100 ) );

I am not sure if anyone from the Tree house team can see this message and specially Mr. Dave, i would like to just give my sincere thanks for putting together such a complex material in such an understable fashion for a price of 3 or 4 tasty espressos a month. Before coming to Tree House i tried 5 different platforms (all of them gave me materials upon materials to prepare) I couldn't understand it all so i found some paces where it was one on one learning and i could have made a better sense of it all and then quickly found out that it was very expensive and what you learn for that price might or might not help you create a simple quiz (at least $4000 for 2 month just for the basics you guys teach here for $25 a month which $50 for two month): So i was disencouraged, but knew that there has to be a platform other than Khan, Solo, Udacity and others i tried where i can just understand a little bit to see a reason to continue because i really wanted to learn, then thanks for your adds on youTube, i check it out and its been 2 weeks: I am not great at it but i have far more understanding of everything i am learning on your platform than i did with other platform for 4 month prior. And it's fun. I can't wait to see what's next. Thank you TreeHouse

Mirali,
If you just want to print the error message on an alert window, just replace the "throw new Error..." for a simply alert message. Ex. alert("Error with the number");
I also found a small bug on your code. As we learned during this course, once a function returns a value it ignores the rest of code within the function. (a function can only return a single value). Therefore, I suggest you to move the "return Math.floor (Math.randon()..." line of code to inside the else {} if you want the error message to show up.
Thx!
