Currently Playing: Promisify functions and avoid callback hell | async javascript

In this video we look into the process to promisify functions so that we do not need to work with callbacks, instead we work with javascript promises. We create a promisify function as a wrapper and then pass the original function to it and get a promisified function in return. This promisified function returns us a promise with which we can do the usual stull like .then() or async await.
