Why is this course different?

There are a lot of Vue courses out there. However, few of them cover:

  • Composition API: Vue 3 adds the Composition API, an alternative way to build Vue components. This course focuses on the Composition API and it's benefits.
  • TypeScript: Vue 3 is now written in TypeScript, and so is all of the code in the course.
  • Unit Tests: All professional developers are expected to write tests. All the code we write in this course is paired with tests, to make sure everything behaves as expected.
  • Pacing: We progress quickly, solidifying new concepts by using them multiple times in different contexts, and by writing tests.
