Why JavaScript?
 Ubiquity
 Shipped with every browser for 15 years
 Not just for DOM manipulation anymore
 Feature rich, browser based applications
 Server side (Node.js)
 Desktop (Windows 8)
 Simplicity
 Power and Performance

6. Consulting/Training
But I Hate JavaScript
 Me too, or at least I used to
 DOM manipulation stinks
 Yes, yes it does
 This is the DOM’s fault
 It doesn’t work (the way I think it should)
 That’s because we want it to be like C#
 While it has a familiar syntax, it is nothing like C#…

7. Consulting/Training
Java is to JavaScript as…

8. Consulting/Training
Looks can be deceiving
 Looks like Java and C# but doesn’t behave like them
 Loosely Typed
 “Function Oriented”
 No such thing as “Classes”
 No such thing as “Namespaces”
 “this” isn’t what you think it is!
