What is React and what are the benefits

For efficient programming today, libraries and frameworks are essential elements that significantly speed up development, increase security, and expand functionality individually. React is one of the most popular environments for JavaScript, suitable for realising web interfaces and applications such as frontends and backends, as well as applications and data processing or dynamic and interactive presentation of multimedia content. Due to its popularity, high functionality, and continuous development, the software has become one of the most important libraries for JavaScript.

Is React a library or a framework?

In terms of its functionality and implementation, React is more of a library that can be integrated into an application with JavaScript to extend an application through procedures and ensure the secure execution of certain algorithms. However, due to its unusually high functionality, React is now also considered a fully deployable web framework that allows the integration of various components through its own JSX tags.

The origin of React lies in a universal JavaScript library designed and implemented by programmer Jordan Walke for Facebook, which has been used for the Facebook News Feed since 2011 and for the display and functionality of Instagram since 2012. Not least due to this prominent use, as well as the financial, logistical, and technical support from the corporation, React has a practical advantage over competing projects like vue.js, which are primarily organised independently of commercial sponsors and rely on the voluntary efforts of developers.

What are the special features of React?

With React, it is not a conventional framework, so there are some peculiarities in its use. Firstly, it can be used as a purely locally or globally installed library, making it easy to integrate into existing JavaScript code to extend functionality. However, complex projects can also be fully planned based on the software, providing users with similar options to similarly operating vue.js and jQuery or more advanced frameworks like Angular or Ember.

To achieve high performance, React distinguishes between practically implemented changes in an application tree and unaffected parts that do not require recalculation. Additionally, it offers its own programming language named JSX for simple organisation and rapid handling of both simple and complex tasks. It enables a clear hierarchical structure and allows a combination of HTML and JavaScript in a single document.

Info: React-based site generators like Gatsby or Next.js are also used in the context of JAMstack.

What can React be replaced with in projects?

For React as a library and expandable framework, there are several advantages - however, there are some alternatives for its use. Despite its high functionality and modular extensibility, this versatility can also be a specific disadvantage. It allows very different solutions for specific problems, which, although qualitatively similar, require the user to make a reasoned assessment of the advantages of different approaches.

Other more classically oriented frameworks such as vue.js or Angular offer a steeper and more efficient learning and programming curve, as they provide specific solutions for various tasks in most cases. This highlights a common conflict in programming between flexibility, functionality, and structuring, requiring an individual assessment of the different systems, frameworks, and libraries in productive systems.
