Introduction to Uses of React JS
ReactJs is an open-source JavaScript library that is used to build user interfaces specifically. This is usually used for single-page applications. It is used to handle all views of an application for any web or mobile application. It is also used to reuse UI components. React enables developers to create web applications that can change your data without reloading your page. The main advantage of React JS is that it is scalable, simple and fast. It also corresponds to a view in the MVC template. It usually acts as a combination of JavaScript libraries or frameworks.
Top Uses of React JS
Please find the below sections, where React JS has been used widely and effectively. Below is the list of top 10 uses are as follows:
Creation of Dynamic web applications is easier
Earlier creating a dynamic web page required a lot of complex coding. It needed specific HTML strings for dynamic web pages. Using ReactJS is no more an issue. It makes use of JSX which has a particular syntax and lets HTML quotes and tags to render particular subcomponents. In addition to this, it also supports building machine-readable code and mixes components into an individual variable file. In React regular JavaScript is not used for creating its templates.
It increases productivity and also helps in maintenance
Reusing components is the major advantage of React JS. Even Facebook has implemented React as it facilitates the reuse of system components. A developer can start with usual components like checkbox, button, etc. Once this is done you can move to wrapper components comprised of internal logic which makes it easier to manipulate and define objects used. This ensures consistency of application and facilitates code maintenance. Many companies like Walmart tend to use ReactJS. As all companies have common components like payment form elements, image carousel, bread crumbs, for example. Here comes into picture the reuse of components. Also to enable version management and further install components there are coding standards defined to maintain uniformity. This also enhances the speed of the application, which enjoys more customer retention.
Ensures faster rendering of Virtual DOM
The performance of any application depends upon the structure on which it is built. For building a high load application this is one of the major factors which is to be considered. But engines that are used these days cannot ensure bottlenecks because DOM (document object model) is tree-structured and even small layers can make drastic changes. To resolve this Virtual DOM was introduced. ReactJS can be used for heavy loaded and dynamic solutions. It is a virtual representation on the document object model and checks if all changes are applied to the virtual DOM. The real DOM tree is later updated and it also ensures that minimum time is consumed for this purpose. Using this method guarantees better user experience and performance.
It ensures to have a stable code
ReactJS uses downward data flow. This is because it ensures that smallest of changes that happen in child structure do not affect the parents. When an object is changed by a developer it needs to be made sure that only the particular objects are updated and that just its state is modified. The data is bound together with the object and this structure sees to it that code stability and application performance is maintained.
Flux and Redux architecture
Flux architecture was developed by Facebook for its various web applications. It is similar to React components by its unidirectional flow. This architecture has action creators that help in creating action from method parameters. It also maintains a library for these methods. All these actions are kept together by a central dispatcher to update stores. All views are updated as per the stores. There is also Redux which is an improved version of flux architecture. It has a single store which is not present in flux. Redux also enables a feature where middleware can be defined to intercept dispatched actions.
It has SEO Friendly features
Whenever there is a common search engine failure to read JavaScript at that time ReactJS runs on a server, renders and returns virtual DOM to browser through a regular webpage. uses of ReactJs has this ability to deal with failures efficiently. With many improvements happening daily at Google we cannot forget other search engines like Yahoo, Bing, etc. Also, microformat cases like Open Graph, Twitter, etc. should also be considered.
A helpful developer toolset
Another important uses of React JS is a user-friendly development platform. The two major tools provided are React to Developer Tools and Redux Developer Tools. Both these tools can be installed as Chrome extensions. React developer tool is used for inspecting react components that lie in a hierarchy and are used for introspecting current properties and states. It also helps to view component hierarchies, discover child and parent components as well. When using Redux you can observe various dispatched actions, current store states and check changes on stores. The different dispatch actions or modify stores with different changes can also be reflected and viewed instantly. A user can also record and go back to any previous states of the application for debugging purposes.
React Native is great for mobile application development
React provides similar design patterns to facilitate the transition process between web and mobile application development. Using JavaScript and React you will be able to build high-end UI apps that are supported by both Android and iOS systems.
Easy to learn
ReactJS is not a framework but a library that brings together objects and focuses on a particular thing to get it done properly. It is the view controller in MVC architecture. Any developer who knows JavaScript can easily understand React, learn its basics and build an overwhelming app.
It is used by most Fortune 500 companies
React is used worldwide due to its easy nature. Once you learn it you have scope in all major companies. Companies like Airbnb, Tesla, etc. use React Native for their applications. You can get a great career once you learn ReactJS.
Conclusion
Considering all the uses of React JS we have seen it can be said that ReactJS is non-risky, responsive and advanced. It can build high-end applications easily and all data changes can be applied repeatedly. It helps developers with virtual DOM which is much faster and user-friendly.
