What Is React.js, a Library or a Framework?

React.js is one of the most popular front-end JavaScript libraries with which a developer can develop web applications. That means it’s a collection of resources with relevant information that can be used on a software development project.

A library differs from a development framework, which is a conceptual structure, a method for addressing and solving the development needs. There are several frameworks that can be used with React.js when coding an application, such as Create React App, Shards React, Redux, and React DnD.

React.js Development: What is React.js Used For?

React.js is specifically used for developing and building user interfaces for single-page applications. A developer uses React.js when designing the view layer of both web and mobile apps. It also can be used when programming reusable UI components.

Is React.js Frontend or Backend?

Since React.js functions as a way to design the view layer of web and mobile applications, it’s used on the front end of a development project. The front end always deals with the layers the end user will actually see, the elements with which they will interact, and the functionalities they will explore directly. The back end, on the other hand, is where you will have all of the coding, the theoretical structure that will support and work in parallel with what is going on in the front end.

React.js Components

Components are bits and pieces of code that can be reutilized and function as building blocks of the application’s user interface. React.js components are similar to JavaScript functions, except they work in isolation and return HTML. There are 2 types of React components: class components and function components.

React.js Compared With Other Libraries

  • Node.js vs React.js

    Just as React.js, Node.js is a JavaScript-based technology. While React.js is used to design and develop the user interface, that is, the front end, Node.js will be employed for programming the back end of the application. Node.js is effective and lightweight, and uses an event-driven and non-blocking I/O model. Developers and engineers can use it for hosting APIs, serving HTTP requests, and accessing the database.
  • Angular.js vs React.js

    Angular is an open source JavaScript framework built using Typescript that can be used by developers to create interactive web applications. It provides an app of relatively small size, but has a considerably steep learning curve, mainly due to its large number of functionalities.
  • Next.js vs React.js

    Next.js is an easy-to-use production framework for React.js that can expand its capabilities when used alongside the development. It can streamline the process providing advantages such as pre-rendering, routing, code splitting, and webpack support.

Is React.js in Demand?

Thanks to its many advantages, React.js is currently one of the most in-demand development technologies. React.js presents high code stability, reducing the impact of changes in the code file. It also offers a robust toolkit with a variety of debugging and design tools. 

React.js is an SEO-friendly technology, which is something that many developers and companies value and strive for nowadays. Last but not least, its popularity has sprung a strong development community, filled with engineers that interact regularly with each other and share best practices and updates.
