I am currently writing a node js library. Now I came up with the question 
what would be the best approach to indicate a usage error by the programmer.

For example if I got the following function in my public API:

    function doSomething(aNumber) {
        // ...
    }

and I need to make sure that aNumber actually is a number, what way of 
error handling should I go if the API user passes a parameter that is not.

By convetion functions in node should return an Error object if an error 
occurs. But in my case this is no error the programmer should catch.

So my question is what would be the most appropriate way to maybe simply 
"end" the program with an error message, telling the programmer that he did 
not use my API in the correct way.
