What is the difference between uneval() and .toSource()

Question

What is the difference between uneval(...) and .toSource()?

The toSource() method returns a string representing the source code of the object.

The uneval() method creates an string representation of the source code of an Object.

Answer 1

One takes a param, the other doesn't. That appears to be the only difference, although the use of both is discouraged.

uneval(object);

Object.toSource();
obj.toSource();

Non-standard

This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

I'd stay away from this feature. There's likely a better way to accomplish what you're trying to do.
