If you pass the pointer (address) of a function as an argument to another, when that pointer is used to call the function it points to it is said that a call back is made. A callback is a function called at the completion of a given task; this prevents any blocking, and allows other code to be run in the meantime. The Node.js way to deal with the above would look a bit more like this: function processData (callback) { fetchData(function (err, data) { if (err) { console.log("An error has occurred. The callback is basically any executable code that is passed as an argument to other code, that is expected to call back or execute the argument at a given time. We can define it in other words like this: If the reference of a function is passed to another function argument for calling, then it is called the callback function. What is a callback function?
