My solution for the coding challenge:

const userNumb = +prompt('Gimmi any random number that you want!');
const userNumbTwo = +prompt('Gimmi another number that bigger tham the first one!');

if (!userNumb || !userNumbTwo){
  alert('Gimme a real number dummy');
} else { 
const randNumGenerator = Math.floor( Math.random() * (userNumb - userNumbTwo) + userNumbTwo ) +1;
const message = `Here is a random number from ${userNumb} to ${userNumbTwo} and that is your random number: ${randNumGenerator}`;
alert(message);
}

Since 0 is not allowed here, it doesn't make a difference; but be aware that when using + for number conversion, an empty response will be converted to a 0, but parseInt considers it to be NaN.

Perhaps this exercise should allow 0 as a choice. For advanced practice, you could try adjusting this code to allow 0 (but not a blank response) to be one of the numbers.
