Class Outline

1. Quick JavaScript Recap
   1. Intrinsic data types (String, Date, Array, etc)
   2. Functions
   3. DOM is not JavaScript
   4. XmlHttpRequest is also not JavaScript
   5. JSON
2. Advanced JS techniques
   1. functions with flexible number of arguments
   2. Using the || as a coalescing operator
   3. Passing functions as arguments to other functions
   4. Anonymous functions
   5. Merging objects
   6. Using the [ ] operator to access object properties or methods.
   7. eval( )
   8. call() vs apply()
3. OO Aspects of JavaScript
   1. Leveraging JavaScript's OO Features
      1. You have objects in your server code, you should have objects in the client scripts too
      2. Client script objects are meant to deal with client-related problems
   2. Creating simple objects
      1. Properties
      2. Methods
   3. The perils of "this"
   4. Extending Objects
      1. That's what a Dynamic language is
      2. Prototype-based programming
      3. Creating prototypes (classes)
         1. Properties
         2. Methods
      4. Extending classes
      5. A word on Dynamic languages
         1. Duck Typing
         2. Runtime errors
         3. Scary? No, flexible and productive
4. Production-grade JavaScript
   1. Where to put JS
      1. Inline (in tag attributes like onclick)
      2. In <script> blocks
      3. In external files
      4. Performance implications of each alternative
      5. minifying vs. obfuscation
      6. gzipping
      7. combining files
   2. Coding standards (Yahoo!/Crockford)
      1. JSLint
   3. Unicode issues
   4. Error handling
   5. Debugging JS
      1. tools
      2. Firebug in Firefox
   6. Unit Testing
      1. Dynamic languages go hand-in-hand with UT.
      2. What are unit tests?
      3. JSUnit
   7. Code documentation
      1. JSDoc
5. Prototype.js
   1. what is, who wrote, who uses, who maintains
   2. Extensions to JS classes (String, Array, Object, etc)
   3. String extensions in detail
      1. escapeHTML, evalScripts, gsub, toQueryParams, etc
      2. Templates
   4. Enumerables
      1. loops
      2. iterators
      3. list operations
   5. Base class inheritance
   6. Utility functions

      2. Updater
      3. PeriodicalUpdater
   9. Extending Prototype
      1. Adding your own Element methods
      2. Inheriting from Ajax.Request
   10. Where to get more info (lists, trac, docs)
6. script.aculo.us
   1. what is, who wrote, who uses, who maintains
   2. Effects
      1. Core effects
         1. Opacity
         2. Move
         3. Scale
