Thanks for bringing this to our attention @piouson. We do want valid answers like yours to pass.

This seems like a pretty simple fix -- the regex in the current tests expect opening and closing curly braces ({ and }), so we can make those optional with the ? quantifier.

I believe the tests should be changed to

    testString: assert(/\((function|\(\))(=>|\(\)){?/.test(code.replace(/\s/g, "")));

and

    testString: assert(/}?\)\(\)/.test(code.replace(/\s/g, "")));

Would you be interested in submitting a PR to fix this?
