Reference a function inside an IIFE

Question

I have the following logic:

var first_function = (function(d3, second_function) {
  function third_function(param1, param2) {
    /* do stuff here */
  }
})(d3, second_function);

Outside of an IIFE structure, to access the third function, I could normally do something like:

first_function.third_function(data1, data2);

Where am I going wrong?

Answer 1

Its not returning it, so the function is just evaporating. You can do something like this:

var first_function = (function(d3, second_function) {
  function third_function(param1, param2) {
    /* do stuff here */
  }
  return third_function;
})(d3, second_function);

Then, you can access it like this:

first_function( paramForThirdFunc1,paramForThirdFunc2);
