How is JavaScript different from Java?
What are undefined and undeclared variables?
What is an expression?
What is a statement?
Give an example of a function declaration
Give an example of a function expression
Explain what the DOM is and some best practices for interacting with it.

The code you see below is a funny building of chained API :) it is a particle emitter for flame throwers. look at the running demo. I love the end of the flame. all in a single chained instruction. Recently i did all my libraries with chained api and i like it. the lib used below is fireworks.js. This particular emitter is a bit too much chained tho :)

but still i look at the size of the source and at the effect on the screen... you got a pretty cool looking effects for 60lines of javascript. maybe i should just break it in several instructions... would be artificial but hey :)

	// <script type="application/javascript;version=1.8">
	// (necessary to make `let` work)
