Issue starting up server using nodeJS Express.
When I started a nodeJS Express server, it was all good, until after I started my server a couple of times, it stated that a server is already running off the port that I gave it on this repl. So I go to change the port and it wont refresh to my changes because I can't identify what port I want to see on the url.
Make sure you're using port 3000. If that doesn't work, either for the repl or crash the server by breaking the code and restarting it with port 3000.
