properties

• keyword
• properties declaration
  • a script may contain a properties declaration to define an initial set of property values for that object
  • syntax:

properties

  propName: propValue,

  propName: propValue

end properties

• Typically, properties are defined at the beginning of a script, but may also appear at the end, or between handlers. If a properties declaration appears after  some initial statements in a script (an initial handler), the properties declaration will mark the end of the initial handler -- any statements after the properties will not be executed.
