Well, you might want to start with a book or just one of the millions of free online tutorials, but, you can
look thru the archives here if you have questions. Most beginner questions have already been answered
here. Otherwise ask you questions and we will help!
By the way, a good source of tutorials is W3Schools. They have tutorials on just about any subject and I
find it very helpful for new programmers. Here is a link to their site. You can select the language at the top
and then a subject for that language on the left. A good place to start.

But, of course, please come here to ask your questions. We can help. And, welcome to the site!
