Someone asked me this question on Askolo
The best way to learn programming is to do it. I think there’s two tracks that you need to pursue: learn the fundamentals of programming (aka, the boring, but important stuff), and a project you want to do.
Or if you’re a cheap bastard, you can start with http://www.w3schools.com/js/ which gives you examples you can play with right in the browser! It’s important that you play with the examples. That’s how you get to know how it works! Change something, see what it does!
The other half is to pick a simple project that you’d like to do. The idea is to pick something that’s not too hard for you (important!), but something you’re really really excited about building (double important!). It can be stuff like make every image in a webpage be upside down as a prank for your friends. Or implement this XKCD comic: http://xkcd.com/1031/ I can’t really tell you what to pick, since you need to pick something exciting to you, so you’ll want to work on it, even when your friends ask you out for a kegger. But also make sure it’s doable. That’s hard to judge when you’re just starting out, but one way is to ask a programmer friend that can appreciate beginners.
After you get the basics from w3schools, I’d say it’s important to learn JQuery. http://jquery.com/It’s the sane was of manipulating the stuff you’d see on the page.
After that, you’re ready to tackle:
– Write a little, test a little. That way, you know what you changed since last time that broke it. Don’t try to write the entire thing all at once, and then run it.
– Make sure you check that you’re not missing semicolons, and all your braces, parens, and brackets match. Computers are finicky.
– If you have questions or get stuck, search on stackoverflow.com They have lots of answers.
