      Vite is an alternative to the Vue CLI and uses Vue 3 by default. It's noticeably faster because it does NOT use webpack to bundle your code and instead makes use of native ES module imports. We’ll be using Vite throughout this series so it's a good idea to quickly get familiar with it.

      Vue 3 no longer requires a single root node for components. Let's review a few examples, while also discussing how to satisfy the linting rules in VSCode.

      The Composition API is the biggest change in Vue 3. It’s completely optional but worth understanding in case you come across code that uses it. In this lesson, we'll convert a simple Todo app using the traditional options API to the composition API.

      Teleport was ported from the popular Portal Vue library in Vue 2. It allows you to render pieces of code in other parts of the DOM.

    7. EPISODE 7

      Run Time 2:55

      Free

      Let's take a look at the change detection caveats for objects and arrays that were present in Vue 2. Vue 3 fixes these as they move towards a proxy-based API for change detection.

      Let’s take a look at the ability to add multiple v-models on a custom component. This allows you to keep state synchronized between a parent and a child component.

    9. EPISODE 9

      Run Time 4:24

      Free

      Let's discuss the Global API changes in Vue 3, and the ability to use instance methods as opposed to global methods in Vue 2. Further, we'll take a look at Global Tree Shaking.

      Run Time 10:56

      Free

      Let's discuss some of the breaking changes in Vue 3 and go over the alternatives. We'll take a look at Initializing Vue, Event API changes, filters, inline templates, and v-model.

      Suspense allows us to render fallback content before your component is ready to be rendered. It’s a cleaner way to handle loading states using a Suspense component and different slots for each of the states.

      Note: This is an experimental feature and subject to change.

    2. EPISODE 12

      Run Time 5:20

      Free

      Let's take a look at script setup, which helps reduce the boilerplate in the setup method for the composition API. We'll also review <style vars> which allows us to reference state inside of our style declaration.
