improvements

[PedroFonsecaDEV]

So I made some improvements.
Your Bug:
The bug was because you were printing on the console the error message from your fetch() instead of considering that error as a BAD URL (if fetch fails because the URL is BAD).

-Request only HEADERS. (optimization)
Now your fetch just requests the HEADERS. It will save time and space for your application.

-Timeout of 1.5secs (optimization)
If a server does not send a life-signal in 1.5secs, your fetch will throw an error.

-Callback hell.
You were in callback hell. A lot of "IFs" nested and so on. (David has a good video about it. I will send the link to you).
I tried to change it, but you can still working on it.

-function messageOne()
I just put your message inside a function to help us exit from callback hell.

-Add feature: request only headers.
-Add feature: fetch timeout.
-Propose of "-v" instead of "v"
-Better Formatting. (No callback hells)
-Probably I'm gonna create a new pull request with more improvements during this week.

Please let me know what do you think about these suggestions.

Thanks.
Pedro
