Only one number generated and no thrown error message..Help?

My code is identical to the video solution, but the console only shows one number and no error message no matter how many times I call the function (correctly or incorrectly). It seems like the code for the generator is the only thing passing for some reason. Help would be appreciated!

my code:

function getRandomNumber (lower, upper){
  if (isNaN(lower) || isNaN(upper)) {
    throw new Error('Both arguments must be numerical values.');

  }
  return Math.floor(Math.random() * (upper - lower + 1)) + lower;

}

console.log( getRandomNumber(1, 5) );
console.log( getRandomNumber(5, 15) );
console.log( getRandomNumber(1, 'twenty') );

Which browser are you using and how are you running the code, e.g. Workspace, Broswer Dev Tools, CodePen?

I'm not really familiar with Safari, but is it possible you have error warnings turn off in the console?

For the record, your code works fine with Chrome's and Firefox's Dev Tools, although when I tried it using Firefox's Scratchpad from the Dev Tools the error displayed in the Scratchpad, but not the console. It worked from the default input within the console with Firefox, however.

browser: Safari Editor: Workspace

I have not tried to run it anywhere else as of yet.

Thanks for the quick response. I ran it in the safari console without workspaces and it worked as it should. Not sure what the issue was in regards to why the code wouldn't work in workspace, but as long as it's correct and runs elsewhere I am fine with it. Appreciate it!
