Not recieving an error regardless of what arguments get passed

Have the code set up exactly the same and yet my or statement doesn't seem to be getting engaged.

function getRandom(lower, upper = 100) { if (isNaN(lower) || isNaN(upper) ) { throw Error("both arguments must be numbers"); } return Math.floor(Math.random() * (upper - lower + 1)) + lower;

} // Call the function and pass it different values

console.log(getRandom(1, 10)); console.log(getRandom(1000, 1000000));

Hi there, Zach Hope! In both your calls to the function you are sending in numbers. The only way this will throw an error is if one or more are not numbers. When I run this, the error is thrown as expected.

console.log(getRandom("tree", "house"));

Hope this helps! :sparkles:

In the console I was adding paran around one of the numbers thinking it would make the number a string yes was unable to manifest the error though still not sure what’s going on with it
