Built-In Objects

• Remember Objects?
• A combination of properties (variables) and methods (functions)
• use the new keyword and the constructor to create a new object.
• Example: var myName = new String("Spiff");
• where: var states that you are declaring a variable/object instance, myName is the name of the instance, new is the keyword for a new instance, String() is the constructor, and "Spiff" is the parameter passed into that constructor.
• Can be built-in or user defined.
• We've used some built-in objects.  String, document, etc.  We'll use more.
