When you use React JS, you will be able to develop interactive UIs without too much of a hassle. You can design simple views at every stage of your application and React JS can help you render the right components. Also, with React JS, you won’t have to worry about changing the technology stack that already exists at your company. You will still be able to create new features without the need to rewrite any of the existing codes. React is not here to give a complete “application library”. Instead, it is designed such that user interfaces can be built using it. As a result, it may not have all the tools that developers generally need when they’re building an application from scratch. What this means, however, is that the developer will be able to choose the libraries they want to use to accomplish the tasks. As the library has matured over the last few years, a few common patterns have emerged that are commonly implemented by developers in their own apps.
