How can you improve your JavaScript skills with ES6+?

1 What is ES6+?

ES6, or ECMAScript 2015, is a major update to JavaScript that introduced many new features and enhancements, such as arrow functions, classes, modules, promises, template literals, and more. ES6+ refers to the subsequent versions of ECMAScript that have been released annually since 2016, such as ES7, ES8, ES9, and so on. Each version adds some new features and improvements to the language, such as async/await, spread operator, object destructuring, optional chaining, and more.

2 Why learn ES6+?

Learning ES6+ can benefit your JavaScript skills in several ways. First, it can help you write cleaner and more expressive code that is easier to read and maintain. For example, you can use arrow functions to write shorter and more concise function expressions, or use template literals to create dynamic strings with embedded expressions. Second, it can help you use modern and advanced features that can enhance the functionality and performance of your code. For example, you can use promises and async/await to handle asynchronous operations more elegantly, or use modules to organize and reuse your code across different files. Third, it can help you stay up to date and compatible with the latest standards and best practices of JavaScript development. For example, you can use transpilers and polyfills to make your ES6+ code work on older browsers, or use linters and code editors to check and format your code according to the latest conventions.

3 How to learn ES6+?

If you're looking to learn ES6+ and improve your JavaScript skills, there are many resources and tools available. Online courses and tutorials, such as Wes Bos's ES6 for Everyone or Tyler McGinnis's Modern JavaScript, can teach the basics and details of ES6+ features and syntax. Additionally, there are books and articles such as Exploring ES6 by Axel Rauschmayer or ES6 & Beyond by Kyle Simpson that explain how to use ES6+ in projects. You can also consult official documentation and references of ECMAScript and JavaScript to learn more about the specifications and usage of ES6+ features. To practice your skills, you can build projects and solve challenges on platforms like CodePen, CodeWars, or Frontend Mentor. Finally, you can read blogs and newsletters such as JavaScript Weekly or 2ality to stay up-to-date with the latest news and trends in JavaScript development.
