Vue 3 brings forth an improved reactivity system, introduces the Composition API for organizing component logic in a modular fashion, enhances performance with a fresh virtual DOM and offers enhanced TypeScript integration. These enhancements position Vue 3 as an appealing option for constructing contemporary, scalable, and easily maintainable web applications. 

In this course, you’ll cover the fundamental concepts of Vue 3. You’ll start with learning the fundamentals of Vue.js, such as Vue instance, template syntax, interpolations, methods, computed properties and directives. Next, you’ll learn how to use the Vue components, custom components, component options, component lifecycle, prop validation, and named and scoped slots. You’ll also learn how to use routes, navigation and navigation guards in Vue.

After taking this course, you’ll have a solid understanding of Vue and you’ll be able to create more scalable, maintainable, and testable Vue-based applications that can handle complex states and data.
