Discussion on: How can I detect the presence of varargs in JS function?

[Andy Wright]

Would you elaborate on what you are trying to achieve please?

I'm working on HotTea, and I'm creating an overloads function.

One of the things it has to do is check if there are methods with varargs parameters.
I want to check as a last resort, in case there are no overloads with X amount of parameters (where X is the amount of arguments you provide).

Something like this:

const add = overload("myFunction", [
  function add(x, y) {
    return x+y;
  }
  function add(x, y, z) {
    return (x+y)+z;
  }
];

What it does internally is looks through this list and checks some criteria.
The criteria is:

• The length is the same.
• (If using typedOverload) The types match

If I check the list, I need to include the varargs (I may also need a distinct way of doing this).

Hopefully this helps explain my goals better.
Thanks. Cheers!
