How can I call an exported function from itself?

Question

how do I restart a Javascript function (node.js environment) from inside that has been declared like this:

exports.myfunction = function(parameter){
   //myfunction(); does not work
}

Answer 1

Name it :

exports.myfunction = function myfunction(parameter) {
//                            ^^^^^^^^^^
    myfunction(); // does now work (but leads to a stack overflow obviously)
}

Answer 2

exports.myfunction = function(parameter){
   exports.myfunction(); // this works
}
