Get a list of currently defined functions in node.js

Problem

Is there any function that can be used to list all of the currently defined functions in node.js? I'd like to create a function like this:

function getAllDefinedFunctions(){
    //return all the functions that are currently defined
}

Solution

You can use a for / in loop to loop over all properties in this (the global object) and check whether typeof this[name] is 'function'.
