# These are my notes from the PragProg book on CoffeeScript of things that either 
# aren't in the main CS language reference or I didn't pick them up there. I wrote 
# them down before I forgot, and put it here for others but mainly as a reference for 
# myself.

    USAGE:
   -- Yes you NEED to properly escape the string literals, or just alternate single and double quotes 
   -- to access any global function or property you should use window.functionName() instead of just functionName()
   -- this example assumes you passed this context to your handlebars template( {name: 'Sam', age: '20' } ), notice age is a string, just for so I can demo parseInt later
   <p>
     {{#xif " this.name == 'Sam' && this.age === '12' " }}
