console.log looks like debug code. Are you sure you do not want to remove it?

The parameter e is not used and could be removed.

Consider using undefined instead of void(0). It is equivalent and more straightforward to read.

Usage of the sequence operator is discouraged, since it may lead to obfuscated code.
