(static) freeze(object) → {Object}
Freezes an object: that is, prevents new properties from being added to it; prevents existing properties
from being removed; and prevents existing properties, or their enumerability, configurability, or
writability, from being changed.
In essence the object is made effectively immutable. Returns the object being frozen.

Returns a property descriptor for an own property (that is, one directly present on an object,
not present by dint of being along an object's prototype chain) of a given object.
On environments that do not support it natively, this is just a sham to allow code to work.

(static) hasOwn(object, property) → {boolean}
Returns a boolean indicating whether the object has the specified property.

that object; unlike the $.Object.has function, this method does not check down the object's prototype chain.

Some gotchas to watch for, not all browsers agree on what properties are enumerable:
IE 6 to 9: Error: description, message
IE 10: Error: description
FF 3 to 5: Error: message, fileName, lineNumber, stack
FF 3 to 3.5: Function: prototype
Chrome 5 to 9: Error: message, stack
Chrome 10 to 13: Error: arguments, type, message, stack
V8 Error object has: captureStackTrace, stackTraceLimit
Opera 10 to 12 & next: Error: message
Opera 11.5: Function: prototype
Safari 4 to 6 & next: Error: message
There are most probably other native objects that do not agree: Object and Array should be fine in all
environments..
