What is the best way to learn javascript?

Well, If you do Khan Academy, there's a free ProcessingJS Tab.

ProcessingJS is like Javascript.

I learn there and I'm pretty good at Javascript only for 2 months.

// or, you can learn HTML, CSS, SQL in there.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
