I've had this question as well, haha. But you'll learn.
So there are two solutions here; one using a localhost and one just simply viewing the file.
I'm not sure what device you're on, but to view your file, just simply double click it as you would do to open any other file. Then you will be able to see your code and what you're programming.
The second solution is the use of a localhost; it's basically a test environment for your website to view it during development.
To set up a localhost on a Macintosh device, you simply go to the Finder and search for Terminal, later open it and write; python -m SimpleHTTPServer.
If you have a folder for your files as well (which is recommended for future reference), just use cd and type where it is. The easiest method would be placing it on the Desktop, and then write in the Terminal; cd Desktop -> cd the-folder-you-have-your-code-in and then write python -m SimpleHTTPServer.
To access this server, just type localhost in the search bar where you'd search for items on the web.
Hope this helps you, and welcome to the developing society!
For future reference, when you become a full-fledged developer, don't use Homestead/Laravel, it's a pain in the ass when you don't understand it. Use WAMP, MAMP, or XAMPP based on what device you're on.
