We already stated that ReactJS is JavaScript library used for
building reusable UI components. Definition can be found on React
official documentation −
React is a library for building composable user interfaces. It encourages the creation of reusable UI components which present data that changes over time. Lots of people use React as the V in MVC. React abstracts away the DOM from you, giving a simpler programming model and better performance. React can also render on the server using Node, and it can power native apps using React Native. React implements one-way reactive data flow which reduces boilerplate and is easier to reason about than traditional data binding.
React Features
- JSX − JSX is JavaScript syntax extension. It isn't necessary to use JSX in React development, but it is recommended.
- Components − React is all about components. You need to think of everything as a component. This will help you to maintain the code when working on larger scale projects.
- Unidirectional data flow and Flux − React implements one way data flow which makes it easy to reason about your app. Flux is a pattern that helps keeping your data unidirectional.
- License − React is licensed under the Facebook Inc. Documentation is licensed under CC BY 4.0.
React Advantages
- React uses virtual DOM which is JavaScript object. This will improve apps performance since JavaScript virtual DOM is faster than the regular DOM.
- React can be used on client and server side.
- Component and Data patterns improve readability which helps to maintain larger apps.
- React can be used with other frameworks.
React Limitations
- React only covers view layer of the app so you still need to choose other technologies to get a complete tooling set for development.
- React is using inline templating and JSX. This can seem awkward to some developers.
