I'm trying to give my plugin callback functionality, and I'd like for it to operate in a somewhat traditional way:

myPlugin({options}, function() {
    /* code to execute */
});

or

myPlugin({options}, anotherFunction());

How do I handle that parameter in the code? Is it treated as one full entity? I'm pretty sure I know where I'd place the executory code, but how do I get the code to execute? I can't seem to find a lot of literature on the topic, so thanks in advance for your help.
