Staying up to date with JavaScript’s changes saves you from being stumped by syntax.
In this course, you’ll learn about all latest language features published with ES2019 and see how they solve problems, using the example of a Nuxt.js application.
From optional catch binding to creating an object from a list of key-value pairs, you’ll learn the benefits of these new features and understand when, why, and how to use them in your legacy projects and upcoming work.
