Modern JavaScript

"ECMAScript is a standard for several scripting languages, including JavaScript. Since 2015, a new version of the ECMAScript spec has been published annually. These versions-ES6, ES7, and ES8, respectively-don't deprecate any old syntax, so you'll be able to safely run legacy ES5 code in future web browsers or standalone JavaScript engines, but they also include lots of new syntax elements that make the process of writing JavaScript code more productive."

"Join expert Yakov Fain for a hands-on, in-depth exploration of the latest JavaScript features and major syntax constructs beyond ES5 and learn how to use them to develop web apps that can be rendered by all browsers. While most modern browsers already support ES6, you'll learn how to use modern JavaScript syntax in development and compile it into the ES5 syntax so that your web apps can be rendered by any browser."

"What you'll learn and how you can apply it By the end of this live online course, you'll understand: How to write apps using the latest JavaScript syntax How to work with asynchronous functions using the new async/await syntax How to modularize JavaScript code with ES6 modules And you'll be able to: Transpile code from the newer JavaScript syntax into the older one Appreciate the benefits of modern JavaScript Start using modern JavaScript in existing projects"

ECMAScript issues annual versions since 2015, including ES6, ES7, and ES8, that add modern syntax while preserving ES5 compatibility. Modern features such as async/await and ES6 modules simplify asynchronous programming and modularization. Developers can author code using modern syntax and transpile it to ES5 to ensure broad browser compatibility. Practical skills include writing apps with modern JavaScript syntax, handling asynchronous functions with async/await, modularizing code with ES6 modules, and using transpilers to integrate modern JavaScript into existing projects. A machine with Chrome and ES5/HTML familiarity is useful for practice.
