What is ReactJS?
React was created by Jordan Walke, a software engineer at Facebook, who released an early prototype of React called “FaxJS”. The current stable version is 17.0.1, released on 22 October 2020(with smaller incremental updates since then).
The core objective of ReactJS is to provide the best possible rendering performance. It comes from the focus on individual components. ReactJS allows a developer to break down the complex UI into simpler components.
Use of ReactJS and its popularity
React JS has been used widely and effectively. Let’s find out the best use of ReactJS.
1) Create dynamic application easily
Earlier creating a dynamic web page required a lot of complex coding. It needed specific HTML strings for dynamic web pages. Using ReactJS makes use of JSX which has a particular syntax and lets HTML quotes and tags render particular subcomponents.
2) It increases productivity and also helps in the maintenance
Reusing components, it’s a major advantage of ReactJS. A developer can start with the 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.
3) Ensures faster rendering of Virtual DOM
The performance of any application depends upon the structure on which it is built. 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.
4) Code stability
ReactJS uses downward data flow. It ensures that the smallest of changes that happen in a child’s structure does not affect the parents. When an object changed by the 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 are maintained.
5) Flux and Redux Architecture
Flux architecture was developed by Facebook. 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.
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.
6) SEO Friendly
React reduces page load time through faster rendering and quickly adapts the performance in real-time according to user traffic demand, such types of features are not perfectly handled by other frameworks. This aspect of quick rendering is crucial for online success, as we know faster the speed more the number of users.
7) Great for mobile application development
8) Easy to learn
Popularity of ReactJS
ReactJS is highly popular because of its simplicity and flexibility. Many people are even referring to it as the future of web development. It is estimated that more than 1,300 developers and over 94,000 sites utilize ReactJS.
Part of this huge popularity comes from the fact that top corporations such as Facebook, PayPal, Uber, Instagram, and Airbnb use it to solve user interface-related issues. This credibility has drawn a lot of people to the framework.
A comparison of ReactJS to other popular frameworks
Here is a closer comparison of these frameworks.
Both ReactJS and VueJS are exceptional when it comes to speed. In ReactJS, every time a component change, a re-render is triggered for the entire component sub-tree. If you do not want re-rendering, consider using Pure Components. In VueJS, components’ dependencies are tracked automatically during rendering. This means that the system knows the components that require re-rendering after the state changes.
HTML and CSS application
Every HTML structure is expressed through JSX while the latest trends add CSS management inside JS as well. However, VueJS embraces classic web technologies and improves on them.
On performance, Angular vs React; AngularJS becomes relatively slow when there are very many users because anything in its scope changes. Besides, the digest cycle in AngularJS requires running multiple times before stabilizing if a user triggers an update. Whereas ReactJS does not experience this issue because it has a dependency tracking system that uses an async queuing.
The learning steps
For a beginner to get started with ReactJS, the learning step is less steep compared to AngularJS. One only needs to get familiar with JS and HTML in the case of ReactJS.
Compared with other platforms, ReactJS comes out as a stronger framework because of its ability to break down the complex UI and allowing users to works on individual components.
The future of ReactJS
Facebook and the entire ReactJS team have demonstrated a commitment to enhancing ReactJS efficiency.
- ReactJS enthusiasts should expect new render types.
- In the future developers expecting an improvement in error handling.
- Enhancing the experience of server-side rendering.
There are a few reasons why a developer prefers to use React.js:
- They are highly flexible to use across the website.
- You can clean up the coding environment by breakdown the code into libraries for more visibility and productivity.
- It provides a toolset that is open-source and easy to use.
- It supports JSX which is a React extension that allows you to create DOM that enables developers to easily arrange Webpages and add dynamic web content.
Here, I recommended the best react admin template that provides flexible code and design.
Datta Able- Responsive React Admin Template
Datta Able Admin Template made in the React framework for achieving any easy or complex dashboard need. The user doesn’t need any documentation for installing. Datta able to include a 20+ page layout which is easy to customize using page builder. The live customization option shows the change effective immediately which helps you to achieve the desired result. The template is fully responsive and retina-ready.
Gradient Able – React Admin template
Gradient Able is a beautiful admin dashboard template built using react hook and comes with Angular 9. It comes with the default layout version, with limited options, Google optimized, font integration, high speed, mature and sophisticated, extremely well-organized code makes Gradient Able Lite a completely flexible solution for any type of back-end application project.
Consider all these we 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.
