Callback Functions in Javascript Challenge. Can't get it right.

So, this is the exercise:

"In the app.js file, functionRunner executes a callback, log. Convert log in to an anonymous function and pass the anonymous function directly into functionRunner."

The pre-populated code is: function log() {

console.log("Hello World!"); }

functionRunner(log);

I have tried everything and cannot find a solution. Can someone help?

Hi Amelia, So I'm thinking step one, let's convert the log function into an anonymous function:

function(){
    console.log("Hello World!"); 
 }

Step two, rewrite that code so your new anonymous function is passed into the functionRunner function:

functionRunner(function(){
    console.log("Hello World!"); 
 });

or written with a newer syntax:

functionRunner(() => {
    console.log("Hello World!"); 
 });
