React JS Tutorial

Why React JS?

ReactJS provides high application performance. Its components are used to define what should be displayed on the screen when a complex UI is composed with small and isolated pieces of code called “components”. It allows users/developers to create reusable UI components. Large applications that can change data, without reloading the page can be attained using React JS tool. It is also used to handle the view layer for web and mobile applications. Its main purpose is to be fast, scalable, and simple.

React JS:

• suits well to component-based UI

• is single data binding

• is quick and efficient

• flexible in building blocks

• is isomorphic JavaScript

• has large community support

• view and control a single place

• helps in building large applications.

Features of React JS

• Virtual DOM: It facilitates the fast and flexible development of applications. Replication of web pages in virtual memory is enabled through memory reconciliation algorithms. This way, a virtual DOM represents an original DOM. Virtual DOM re-renders the entire user interface with every modification in the web application. Only the components that changed are updated and not all components in virtual DOM representation. This way, the app development process is quicker and cost-efficient.

• JSX: JSX, abbreviated as JavaScript XML, is one of the best features of ReactJS. It is a markup syntax that is much similar to that of HTML. It is used to describe the appearance of the UI of an application. Its syntax creates React components and will be injected into the web page. This way coding building blocks of ReactJs is effortless and simple for the developers.

• One-way data-binding: One-way data flow is the major reason why developers choose ReactJS. It uses unidirectional data flow. Developers can’t edit any component directly. The callback function has to be made use of in order to make any changes in the component. This is called one-way data binding. Flux is a JavaScript app architecture that controls the data flow from a single point. The unidirectional flow of data helps developers to gain better control over the web or mobile applications. This way it is more efficient and also enhances the flexibility of the application.

• React Native: React native is ReactJS’s custom renderer. Native components are used instead of web components in ReactJS. To make it compatible with Android and iOS platforms, react-native converts react code.

• Declarative UI: For creating and interactive user interfaces for mobile and web applications, ReactJS is considered the best. It adequately renders and updates the right components in an event of data modification. Its feature makes the code more readable and simpler to debug since it generates a simple view for each state of the application.

• Component-based architecture: ReactJS has component-based architecture. The UI of React-based web or mobile applications is sub-divided into multiple components. Every component has its own specific logic. JavaScript logic is written instead of using templates. This way, data can be passed throughout the application without affecting the DOM. ReactJS components play a major role in determining interactions and visuals in the applications.

When to use ReactJS?

Developers use ReactJS to eliminate errors in personal biases, build contacts with trustworthy ReactJS development companies to make sure of the viability of the decisions made.

• Interactive Data-Heavy Dashboard: ReactJS offers ready-to-use templates for dashboards. They are not open-source tools. It is very feasible. With proper planning, many components can be reused to make the code more modular. It is a framework that aids in the fast re-rendering of UI components. It is considered the best solution for building data-heavy applications because of its virtual DOM. It ensures smooth and quick updates just by sending data through its APIs.

• Social Networking Web Applications: Every social networking app has been on the top use case for ReactJS since the time it was used to build Facebook applications. Social networking apps have to reload to a new page in response to certain requests. Each page in these apps is built as a SPA using ReactJS. This gives users a top-notch experience like Twitter and Facebook. Communication can be automated between client and server using a web socket. This is to incredibly speed up the process of data flow. 

• E-Commerce Web Application: eCommerce applications have rich features and a seamless user interface. This makes them very successful. eCommerce apps built with ReactJS have good traction now. This is achieved through the exhaustive UI components that are built-in to the ReactJS library. Code reusability helps in building large-scale eCommerce web applications. It reduces both development time and efforts put in to maintain it. It is the most beneficial technology stack for developing web applications and also ensures efficient state management.

• Single-Page Applications: SPA, abbreviated as Single-Page Application, which is highly interactive, is built using ReactJS. React-router is a very good tool that facilitates an efficient single-page navigation experience for its clients. Developers can build and present a complex view with server-side rendering using React.

About This Course:

React JS is a free, open-source front-end library of JavaScript that aids in building user interfaces or UI components. Maintained by Facebook and a community of individual developers and companies, it can be used as a base in the development of mobile applications and single-page applications. React is an efficient, declarative, and flexible JavaScript library. It is widely popular because of its simplicity and flexibility. It is used for building user interfaces. It also aids the reuse of UI components. React JS, for beginners, is also very easy to learn since it is very simple to handle and work with. It is popularly used because of its high simplicity and flexibility. It is also used in building cross-platform applications, but the same code that is used in developing web applications cannot be reused for building mobile applications. React native can help use the same architecture for both web and mobile application development.
