4,688 PointsConvert log in to an anonymous function and pass the anonymous function directly into functionRunner.
//The app.js file originally looked like this:
function log() {
console.log("Hello World!");
}
functionRunner(log);
//My edit on the app.js file was this:
function log( callback ) {
callback();
}
log(() => console.log("Hello World!"));
functionRunner(log);
//I am confused as to where to fix this... The error I received was as follows: "There was an error with your code: TypeError: 'undefined' is not a function (evaluating 'callback()')"
function log( callback ) {
callback();
}
log(() => console.log("Hello World!"));
functionRunner(log);

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

8,225 PointsMDN (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions) describes the following as an anonymous function and I saw similar example at w3cschools.
I think most people would immediately start to think about arrow syntax. But I tried this an it worked and it didn't seem to like my use of arrow syntax, so I guess that was what it wanted. The language i used was "It seemed to accept", which avoids committing to anything beyond passing the challenge.
