20.Object Literal:对象字面量

A JavaScript object literal is a comma-separated list of name-value pairs wrapped in curly braces. Object literals encapsulate data, enclosing it in a tidy package. This minimizes the use of global variables which can cause problems when combining code.

The following demonstrates an example object literal:

var myObject = {
    sProp: 'some string value',
    numProp: 2,
    bProp: false
};
