I only learned the programming basics from a teacher, then self-taught everything I know today and landed a good job. Don't be scared! Have fun instead ;)

You might want to check out my FAQ for new programmers, which should inform you about various stuff I had to learn the hard way.

Yes it can, but be careful because it's full of quirks and caveats. (scope, closures, comparisons etc...)

Once you know those, JS is a very fun language, good for almost anything.

Sure. I never joined any programming class. At the beginning, I even wrote JS with stylo and paper because no computer :D

There is no shortage of materials and tutorials for javascript on the internet and and i believe it can be self learnt. And like all other programming language js has a lot of libraries and will take a fair amount of time to master.

I'm doing it right now :D I just realized I've been learning JS for 4 years

What's really fun about JavaScript is you can run it in any web browser, so as long as you have a computer, tablet, or even a smartphone, you can be testing things out and learning!

Yep! It's simple and powerfull! So dive in!
