You define (and create) a JavaScript object with an object literal:
var person = {firstName:"John", lastName:"Doe", age:50, eyeColor:"blue"};
The name:values pairs in JavaScript objects are called properties.
objectName.propertyName
Or
objectName["propertyName"]
Examples:
person.lastName;
person["lastName"];
One example of the use of objects in kBridge is the position spec.
