They don’t have drawbacks that callbacks have. I am pretty sure you are already using callbacks in your code, but I am not sure if you know how they actually work… Knowing how things really work will help you write your code faster and avoid weird bugs.Promises were created as a better alternative to callbacks. Creating event handlers, making HTTP requests, interacting with the DOM, setting timeouts, reading or writing data to the filesystem, working with databases, etc. You will also see a lot of coding examples along the way.We will be talking about 3 main components of Async JavaScript: Callback functions, Promises, and Async Await.Callbacks in JavaScript are used everywhere. This course was designed to be easy to understand, and therefore there are a lot of visuals in it, especially when we are talking about important concepts. This course was specifically designed for those who want to improve their skills in Callbacks, Promises, Async Await, and Event Loop.
