ReactJS
ReactJS is a flexible JavaScript front-end library that is used to build interactive user interfaces. As it is component-based, this library makes it easy for the developer to even build complex UIs.
While using the mix-and-match approach of multiple frameworks, ReactJS makes it easy by providing hooks that let you interface with other libraries and frameworks. Declarative views make your code more predictable and easier to debug.
VueJS
VueJS is a progressive JavaScript framework that is open source and used to build engaging user interfaces. It is incrementally adoptable and scales between a library and a full-featured framework.
It is light-weight, making it perfect for mobile development. IT is also easy to learn and use. The framework is also compatible with other JavaScript libraries, reduces development time, and delivers quicker debugging solutions.
PreactJS
PreactJS was created as an alternative to ReactJS with a size of 3kb. It is so small that your application code would form a larger part. From buttons to data providers, Virtual DOM components make it easy to share reusable.
Preact’s design lets you seamlessly use thousands of components that are already available in the React ecosystem. PreactJS can be used to build certain parts of an app without complex integration.
EmberJS
EmberJS is a JavaScript framework that’s open-sourced and used to build ambitious web applications. The framework is based on the Model–View–ViewModel (MVVM) pattern.
It facilitates scalable, single-page web applications with minimal coding. EmberJS can be used to create unique desktop and mobile apps as well. It lets you build even complex front-end web applications quickly.
Designed with developer ergonomics in mind, its friendly APIs help developers efficiently get the job done. Ember.js is built for productivity.
With more frameworks being added, developers have more options and they can easily use multiple of these during development.
