JavaScript often abbreviated as JS, is a programming language that conforms to the ECMAScript specification. JavaScript is high-level, often just-in-time compiled, and multi-paradigm. It has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions. Alongside HTML and CSS, JavaScript is one of the core technologies of the World Wide Web. JavaScript enables interactive web pages and is an essential part of web applications. The vast majority of websites use it for client-side page behavior, and all major web browsers have a dedicated JavaScript engine to execute it.

We all know the importance of promises in our life. We even have a special day dedicated to it :) But how well do we know the importance of promises in JavaScript? Well if you don’t know it yet, it’s a great time to know it because they are becoming more and more popular. So what are promises? Let’s try to understand it through an analogy.
Javascript async-await is used to deal with asynchronous code. Async-await is a technique to write async Javascript code in sync manner.
In today's video I'll be demonstrating the usage of async/await in JavaScript (asynchronous functions) and how they give you a much cleaner way to work with Promises.
Ben Nadel demonstrates (to himself) that the return value of an async / await function is implicitly wrapped in a Promise.resolve() call in JavaScript and TypeScript. And, that this will implicitly flatten the Promise chain as the return value is chained.
We are getting closer and closer to launching the Creative Javascript Course. I wanted to share a small portion of the Async Javascript chapter of the course where we will learn everything there is to know about how async code works in javascript. We are going to take a look at all the popular ways async code is being run such as callbacks, promises and the new async await.
