evon

More accurate than JSON and nearly as fast.

An evon encoding is a javascript program that we eval() to accomplish the restore.

This is much more flexible and accurate than JSON, and the speed is still respectable.

Compare:

Feature	JSON	evon
Arrays: non-numerically named properties	Discarded	Restored
Arrays: Sparse entries	All restored as null	Distinction made between null, undefined and non-existent. Length restored accurately
Prototype	Discarded	Restored if object.constructor evaluates to a constructor function
Constructor parameters	No constructor ever called anyway	object.getCtorParams() may return a list of parameters to pass to the constructor upon restoration. Versions for Date etc provided
Circular references	Explicitly bottles out	Restored
Multiple references to same object	Object duplicated	Restored correctly
