###Chapter 3: “Object Literals”

• complex scripts can run to hundreds (even thousands) of lines. Programmers use functions, methods, and objects to organize their code.
• Objects group together a set of variables and functions to create a model of a something you would recognize from the real world. In an object, variables and functions take on new names.
• IN AN OBJECT: VARIABLES BECOME KNOWN AS PROPERTIES, FUNCTIONS BECOME KNOWN AS METHODS
• there are several way to create objects:
  • literal notation is the easiest and most popular way to create objects. var object = { key:value cheackAaialbility : function(){ return this.key - this.key; } };
• you access the properties or methods of an object using dot notation.you can access properitis using square brackets.
  • var objectKey= object.key;
  • var objectKey= object[‘key’];
