About the course

Learn all the exciting new features, improvements, and breaking changes that Vue 3 introduces.

By the end of this course, you’ll know:

How to leverage the Teleport and Suspense features
How to use multiple v-models

Important Vue 3 does not introduce many breaking changes. The breaking changes are covered in this course, and we provide you with solutions for your upgrade process and workarounds where needed.

This means that it doesn’t require a lot of effort from Vue 2 developers to learn Vue 3, or to upgrade existing applications and websites.

Prerequisites In this course, you will not learn Vue.js from scratch. If you are looking to get started with Vue.js, please check out our Vue.js Fundamentals course.
