Performance is its main characteristic, which is why it has been selected for a multitude of high-level projects, as well as facilitating agile, orderly development with a maintainable architecture. Among other innovative ideas from React to improve application performance is the addition of a virtual DOM.
Components are one of the fundamental pieces of React, which basically allow us to encapsulate code, to generate small pieces with limited functionality. Just as in object-oriented programming, where various objects collaborate with each other to solve the goal of complex applications, in component architecture, they are organized and collaborated so that they can implement any advanced application. What is achieved is a modular application, avoiding the so-called spaghetti code that is produced with libraries such as jQuery.
It should be noted that React by itself is a library and not a framework since it deals with user interfaces. However, various additions can turn React into a product comparable in features to a framework. For example, Redux, which implements a pattern by which data flows between application components. In any case, the fact that React is a library is interesting for many developers, since each one can make their applications in a personalized way, applying those additional tools and libraries that best suit the project or the work habits of each one.
Many libraries specialize in data binding, such as Angular, Ember, Polymer, etc. The difference between React and any other alternative centers on the existence of the Virtual DOM, which is basically a representation of the DOM but in memory.
When a view is updated, what changes in React is the Virtual DOM, which is much faster than updating the browser DOM. When React compares the virtual DOM to the browser DOM, it updates only the parts that are needed and not the entire view. This behavior is key in React and causes its high performance, since when data changes in the application, it does not need to update the entire view.
We can't finish without talking about isomorphism, one of the most important features of React. This concept is very interesting in the development of applications that we want to achieve a good position in search engines.
Companies that have already adopted ReactJS have done so for a number of reasons. Here are the most notable adopters besides Facebook.
Using NodeJS, the React library allows HTML to be rendered with the same code both on the server and on the client, reducing the workload required to create search engine-friendly web applications.
