fn(/* ??? */) must return false
- You can only edit
/* ??? */in the script below. - You can only replace
/* ??? */with a valid parameters list. e.g. things liketrue, 1) && (falsear not allowed. - The parameters which you replace
/* ??? */with can't modify other parts of the program (e.g. they can't overrideevaloNumber.prototype). If this code is added to an existing program, it shouldn't be observable. - The result must be exactly
false(result === false), so0or"false"are not valid values.
