Vue 3, the latest version of the popular JavaScript framework for building user interfaces, was officially released in September 2020. With the release of Vue 3, developers can expect a number of new features and improvements that will help them build more powerful and efficient applications. In this blog post, we will take a closer look at some of the most exciting new features in Vue 3.
One of the most significant changes in Vue 3 is the introduction of the Composition API. This new API allows developers to write components using a more function-based syntax, as opposed to the traditional object-oriented syntax used in Vue 2. This can make code easier to reason about and reuse, and also allows for more flexible composition of component logic.
Another important change in Vue 3 is the introduction of the setup() function, which provides a new way of managing component state. The setup() function allows for a more declarative and intuitive way of defining component logic, and also makes it easier to test and share component logic.
Vue 3 also includes improved performance through reducing size and memory usage, improving the compile time and other smaller improvements in its internal runtime .This is achieved through a more optimised and smaller runtime.
Vue 3 also includes a new and improved global API, which allows developers to more easily access and modify the global Vue object. Additionally, Vue 3 introduces many smaller changes and improvements in addition to these, such as improved error handling and better TypeScript support.
The new release includes class-style component API, and a new way to create dynamic component, the v-runtime-template and the v-slot directive.
In conclusion, Vue 3 is a significant improvement over Vue 2 and offers a range of new features and improvements that will help developers build more powerful and efficient applications. The introduction of the Composition API and the setup() function, as well as improved performance and global API, make Vue 3 a powerful and versatile framework for building user interfaces.
