How do I return a function within another function

See this:

var funkyFunction = function() {
      return function() {
        return "FUNKY!"
      }
   }

var theFunk = funkyFunction(funkyFunction())

I need theFunk variable to be assigned value "FUNKY!" from the inner function but I have no idea how to go about it?

With ES6/ES7 You can return a function from within a function without naming the inner function.

const myOuterFunction = () => {
  // the ...args just places all arguments into an array called args (can be named whatever)
  console.log("OuterGuy");
  return (...args) => {
    //Whatever Else you want the inner function to do
    console.log(args[0]);
  };

};

//The way you call this

const innerGuy = myOuterFunction();
const randomVariableThatINeed = 'Yay!';
//Call inner guy
innerGuy(randomVariableThatINeed);

Since funkyFunction is returning a function, the result of invoking funkyFunction can then be invoked:

var func = funkyFunction();    // 'func' is the inner function
var theFunk = func();    // 'theFunc' = 'FUNKY!'
