Vue 3 is a modern progressive JavaScript framework. It is used to create SPA, SSR apps or SSG websites. It has loads of features which improve developer as well as user experience.

Here are the 5 reasons to learn Vue 3.

Improved performance

One of the major goals of the Vue 3 rewrite was to improve the performance of the framework. To achieve this, the Vue team focused on optimizing the virtual DOM and reducing the amount of work that the framework has to do in order to update the DOM. These optimizations have resulted in a faster and more lightweight framework that is better able to handle larger datasets and perform well in production environments.

Composition API

The Composition API is a new feature in Vue 3 that allows developers to use a functional approach to building components. This is in contrast to the object-oriented approach used in previous versions of Vue, which involved using a component's data and methods as the main way to manage state and logic.

The Composition API provides a number of benefits, including the ability to extract logic into standalone functions that can be easily tested and reused, and the ability to use reactive variables and computed properties in a way that is more similar to modern functional programming languages. This can make it easier to write maintainable and scalable code, particularly for larger projects.

Strong TypeScript support

Vue 3 has better integration with TypeScript, which is a popular typed superset of JavaScript. This means that developers who use TypeScript can enjoy improved type checking and better type inference when working with Vue components. This can help to catch bugs early on in the development process and make it easier to write type-safe code.

Improved reactivity system

Vue's reactivity system is what allows components to automatically update when the data they are bound to changes. In Vue 3, the reactivity system has been rewritten to be more efficient and easier to use. This includes the introduction of a new concept called "proxies," which are objects that automatically update when their properties are changed.

The new reactivity system makes it easier to build reactive applications that respond to data changes in real-time, without having to manually specify which data changes should trigger updates. This can make it easier to write code that is more responsive and easier to maintain.

Active community

Vue has a large and growing community of developers who contribute to the project and create a wealth of resources and tools for other developers to use. This includes things like documentation, tutorials, and third-party libraries that can help to extend the capabilities of the framework.

The strong community support means that as you learn Vue 3, you'll have access to a wide range of knowledge and resources to help you along the way. Whether you're just starting out with JavaScript or you're an experienced developer looking to expand your skills, there will be resources available to help you succeed.

In conclusion, Vue 3 is a powerful and efficient JavaScript framework that offers a wide range of benefits for developers. Its improved performance, Composition API, improved TypeScript support, improved reactivity system, and strong community support make it a great choice for building modern web applications. Whether you're just starting out with JavaScript or you're an experienced developer, learning Vue 3 is a valuable investment of your time and energy.
