Vue.js is a framework for building dynamic JavaScript web applications. Vue.js tries to strike a balance between batteries-included frameworks like Angular and lightweight frameworks like React. Vue.js has first-party plugins for functionality that React relies on 3rd-party plugins for, but the functionality is still optional unlike Angular.
What problem does Vue.js solve?
Vue.js helps developers build complex JavaScript applications by giving them the ability to write reusable interface components, manage the state of the application, and official plugins for other functionality like routing.
Vue.js will also update the web page in response to user input and other events that happen within the web application. This saves developers from having to write their own logic to make changes to the web page or to create HTML elements on the page in response to things the user does.
In addition, Vue.js has support for special syntax you can use to embed dynamic code directly inside of your HTML. Vue.js has its own template syntax for this purpose, but developers can also use JSX if they prefer. These tools let developers make HTML templates that dynamically change in response to changes in the application’s state.
