My solution for the Two Number challenge

https://w.trhou.se/ojpda7a098 It's almost exactly the same as the previous challenge. Just add a number and change the if a tiny bit. Comment out line 17 from the original and add const lowNumber, and change the alert on line 19

Currently, the value for randomNumber in line 10 does not use the value of lowNumber. When running the code, I got the alert 15 is a random number between 800 and 1000

This simplified formula assumes the low number will always be 1. To work with any range, the formula should be:

const randomNumber = Math.floor(Math.random() * (highNumber - lowNumber + 1)) + lowNumber;
