Is anyone able to point my toward the "unexpected "("?

I am currently having a hard time with this challenge. It keeps saying unexpected "(", as long as the () is after my function. Am I not correct that a function requires a ()? I would appreciate any help with this. Thank you so much!

Function() => console.log("Hello World!"))

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

function() => console.log("Hello World!")

functionRunner(function() =>
  console.log("Hello World!"))
<!DOCTYPE html>
<html lang="en">
        <link rel='stylesheet' href='styles.css'>
            <p>Open your browser's console to see the results</p>
        <script src='runner.js'></script>
        <script src='app.js'></script>
function functionRunner(callback) {
