Is it good practice to define a function with different arguments list from reference in javascript?

Question

For example, I working with a framework that would invoke a custom function like this:

var ret = Module_Init(index, clk, obj);

The function Module_Init should be defined by user. And in my Module_Init, I only need the first parameter index. So I define it like this:

function Module_Init(index)
{
    m_Index = index;
    // initialize code...
}

It work, but is it a good practice in Javascript?

It's not good practice to pass unused arguments, you could confuse other developers reading your code. This also leads to a messy codebase. Get rid of them if you don't need then. — Dan Starns, Apr 19 '20 at 07:11
IMO it doesn't really matter. There aren't any downsides to doing that, and the code is simpler to follow if only slightly. BTW you made a typo on `Index` — user120242, Apr 19 '20 at 07:11
@DanStarns Since the *framework* is invoking it, I think it's fine. You don't worry about the parameters you often don't use when using `Array.prototype.forEach` either — CertainPerformance, Apr 19 '20 at 07:12
@CertainPerformance my point is, you don't need to declare them in your code. — Dan Starns, Apr 19 '20 at 07:13
I can't really decide if this is one of those questions that should be closed, because the answer really comes down to opinion rather than a concrete indisputable fact. Especially because I think the question about style is a valid and useful one. — user120242, Apr 19 '20 at 07:15
Voted to close as this really is opinion based. Perhaps [*Currying*](https://stackoverflow.com/questions/113780/javascript-curry-what-are-the-practical-applications) is a better approach. — RobG, Apr 19 '20 at 07:35

If you are not going to use them, why put them in the function

The framework pass these parameters. User need to define the function accordingly. But user don't need use all these parameters passing by framework in my case. Thanks. – Koen Apr 20 '20 at 04:22
