How do you pass a named function with parameters without calling it.
Right now the only solution I have seems like a hack but it is to pass an unnamed function that will call the named function.
callback(function(){foo(params);})
Is there a better way of doing this?
The code that you have now, which wraps the call in another anonymous function is perfectly fine, and is a widely used pattern in Javascript.
If you wish to remove the anonymous function, you could instead use the reference to the function with the bind() method. Try this:
callback(foo.bind(this, params));
