Hello, anyone wanna recommend a first website I should make?
Scripting is most useful in request/response roles where AJAX or some other form of client/server transaction is taking place. Using something like Node.js you can set up a server on your local host so you can perfect your XHR stuff without needing an external server.
Of course, there are still DOM roles such as class-switching and other updating, but styling and presentation should still be left up to the CSS, with perhaps some direction from the script. Perfect the CSS and you will be a guru in any design circles.
Your own computer is the best place to perfect all of the above.
