The text in 15.3.4.2 Function.prototype.toString () says:
"An implementation-dependent representation of the function is returned.
This representation has the syntax of a FunctionDeclaration"
Is there a reason this is a FunctionDeclaration rather than a
FunctionExpression? In particular what is the expected behavior for
toString of an anonymous function?
var f = function() {}
f.toString()
In the engines I tried this gave a result like
"function () {}"
with only whitespace differences. This doesn't match the
FunctionDeclaration production due to the lack of an identifier. Whilst
the engine could invent an identifier, I don't see what the advantage
would be and I would be worried about breaking existing code by doing
so. Instead, I think it would be nice to align the spec with reality here.
