JavaScript Callback Functions in JavaScript Introduction to Callback Functions Creating an Anonymous Callback Function


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.

    console.log("Hello World!"); 

    console.log("Hello World!");
