JavaScript Wrap Up

	JavaScript is a versatile programming language … if you know it, you can learn others

The Big Picture

	Without JavaScript, HTML is quite limited
		Only static page-layouts are possible
		JS allows
			Adaptivity … the page can be customized to the browser, site, user, etc.
			Interactivity … users can give information and a response can be displayed: Memory Bank
			Applications … tasks unrelated to documents can be created
			Animations

Big Picture

	Notice the standard HTML process
			HTML is parsed -- read & “decoded”
			During parse JavaScript runs … allowing it to generate HTML, e.g. document.write()
			Browser generates the page from HTML
			After page generated all is quiet until an event happens, caused by user or timer
			Event handlers handle the events, and then all is quiet again

Consider The OC

	Analyze the process for Orange Con
			HTML is parsed
			JavaScript runs …
			HTML generated
			Browser makes page
			All is quiet except for
			events from user/timer
			Event handlers handle
			events, quiet returns

Other Languages

	JS is a “modern” programming language like C, C++, Java, etc.
			Expect to find numbers, strings, Booleans,
			Variables (of same form) must be declared
			There are if-statements & else-statements
			There is a for-statement
			for (j=0; j<5; j++){
			<statement list>
			}
