React.js
React.js is an open-source library for building user interfaces developed by Facebook. Due to the component-based design, it has been widely used and is famous for its nice rendering.
Well-known and thought to be groundbreaking is the often heralded Virtual DOM, which only renders the changed components. This results in optimization in the large app, making it work better than before. Furthermore, Let’s look at the fact that React follows unidirectional data flow, making the debugging process more manageable and increasing application stability.
Like other similar frameworks, React also relies on community contribution and many third-party libraries and utility tools that are accessible to help the developer streamline his process. It offers a level of flexibility to developers in that it can be developed on and merged with other libraries or frameworks for a more personal approach to application architecture.
Angular
Angular JS is developed by Google and is a phenomenal framework with all the features of an MVC framework, not leaving out RESTful services. The data binding capability gives a method through which these two layers can communicate, hence quick integration.
Angular utilizes TypeScript, a superset of JavaScript; TypeScript tacks on static typing, which helps make code better and more manageable. The dependency injection system in Angular provides modularity in implementing an application to enhance application development complexity.
Furthermore, Angular is equipped with an initial set of functionalities like a form validator, router, and HTTP client and interceptor thus, the need to import many third-party libraries is rarely necessary. All things considered, Angular is coming to many organizations as a solid platform for creating scalable applications.
Vue.js
Vue.js is celebrated for its simplicity and ease of integration. Vue offers reactive data binding and a component-based architecture, often viewed as a middle ground between React and Angular.
