7,823 PointsCan someone explain to why isNaN isnt working?
When I type a string in, NaN comes up instead of the new error message
function randomNumber(top, lower) { return Math.floor(Math.random() * (top - lower)) + 1;
if (isNaN(top) || isNan(lower) ) { throw new Error("input is NOT a number");}}

function randomNumber(top, lower) {
if (isNaN(top) || isNaN(lower)) {
throw new Error("input is NOT a number");
}
return Math.floor(Math.random() * (top - lower)) + 1;
}
