Example 3: object literal javascript

// Object literals are defined using the following syntax rules:
// A colon separates property name from value.
// A comma separates each name-value pair from the next.
// There should be no comma after the last name-value pair.

// If any of the syntax rules are broken, such as a missing comma or colon or curly brace,
// an error will be thrown.

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