Output: Now open your browser and go to http://localhost:8080/, you will see the following output.
- We have created a server variable here that uses the HTTP library and called the create server function on this object and this creates a server function that has two parameters which are the request and response parameters.
- Set up our server so it will listen on the port that we want so that we have this server object pass it that port variable that we created to tell it to listen on port 8080 and then this takes a single function that it will call if there is an error potentially or it was successful.
