2. JavaScript Event Handler

The JavaScript event handler contains events centered around the Document Object Model (DOM). Common events include onMouseOver and onMouseOut, onFocus and onBlur, onClick and onDblClick, onChange and onSelect, onLoad and onUnload.

For example, onMouseOver and onMouseOut are frequently used with websites to change an image when your mouse moves over it. The onClick event is used to trigger code upon a mouse click.

3. JavaScript Report Tools Overview

No built-in report writer but because JavaScript most frequently targets website development (a document interfaced GUI), a common solution is to simply output an HTML formatted page with black text and a white background (not much control but it does work for some situations).

7. JavaScript Overview and History

Language Overview: Class-like language with limited but usable class-like and object-like functionality but no formal inheritance nor visibility control, etc.

Target Platforms: JavaScript is most commonly used to extend HTML by executing code on the browser side when visiting a website. It does have other uses including server side scripting and AJAX.

8. JavaScript End of Statement (; is optional)

In JavaScript, using a semicolon at the end of statements is optional. You might think a semicolon then is just another comment specifier but it is not. The semicolon is an optional end of statement specifier. To put two statements on a single code line, you must use a semicolon. However, the semicolon is optional, but probably confusing, when you break a single statement into multiple code lines.

10. JavaScript Custom Routines (function)

JavaScript uses functions and loosely typed parameters. Function definitions must come before their usage so the usual preference when adding JavaScript to HTML pages is to include them between the head tags.
