Introduction to React JS
React JS was primarily launched for Facebook.
It is an open-source, scalable JavaScript library with which you can build intuitive UIs (user-interfaces), particularly for single-page applications. React efficiently handles the view layer for your applications, be it mobile or web apps. Besides, it also helps you split the UI into reusable components.
Seeing how you do not need to have much expertise in HTML and JavaScript, React JS has grown to be extremely popular in the industry for easy front-end web development.
React JS is widely used for front-end web development in the industry due to the fact that you don’t need much expertise in JavaScript and HTML.
What is the need of using React JS?
With rapidly evolving digital transformation in the industry, we are seeing a gigantic hike in the development of modern business-critical applications. These apps are often built upon powerful JavaScript libraries.
Enterprises are striving to gain scalability, as they want to provide their customers with faster speed, exceptional performance and user-friendly experiences in their web and mobile apps. But, the market is flooded with myriads of frameworks today. And, it gets quite overwhelming for software developers to decide which framework will best suit their needs.
React JS offers ease-of-use, faster speed and the ability to scale. It helps developers build big-sized web applications and modify the data without unnecessary page reloads. It solely handles the view layer in the MVC template of the application UI.
React JS has become one of the “bestsellers” when it comes to web application development tools, as it completely revolutionizes your workflow. For this unique transformation, it leverages SEO-friendly abilities, code stability and faster web-page load speed. Apart from this, it is supported by a strong community of users that enrich the React JS library with regular upgrades.
What makes React JS a Best-Seller? Advantages of React JS
-
Boosts Enterprise Productivity
Modern applications are often built upon complex workflow logic and rolling out changes even in a single component can drastically affect other components as well. Thus, rolling new updates becomes quite challenging for the software team. To tackle this, React JS will let you build reusable UI components and that’s the exact reason why React JS is so popular today.
At first, you may begin with the modification of smaller components and then go for core components. Since the user interface components are built upon internal workflow logic, it becomes effortless to define and manipulate them. By the same token, React JS ensures consistent app monitoring and further simplifies codebase maintenance and scaling. These flexible capabilities are highly appealing to developers.
-
Faster Rendering
Building large-sized modern applications call for the evaluation of the overall structure to predict the final performance of the app. Even the hi-tech, state-of-the-art engines and platforms cannot fully guarantee “zero bottlenecks” in the workflow. This is due to the fact that DOM (Document Object Model) is a tree-like architecture and modifying the upper layer will relatively affect the other layers of the UI.
To avoid this, Facebook’s IT leaders have come up with the Virtual DOM solution. It is also one of the core benefits of using React JS, especially for building heavy-load and dynamic apps.
As you can guess, Virtual DOM is a virtual illustration of the real DOM to facilitate the rendering process. If you manipulate the state of the application, the updates are applied across the virtual DOM instead of the real DOM. With the help of “diff algorithm” in React JS, the virtual DOM will evaluate the necessary changes for the real DOM. Such an approach makes sure there are a minimum number of operations carried out on the real DOM, hence reducing the rendering costs.
One thing that facilitates developers is how they need not check the manual DOM updates or manipulation taking place inside the tree. Developers simply need to upgrade the UI components as per the business needs, the React will handle the rest. This offers developers top-notch experiences and efficient performance.
-
Code Stability
JavaScript and HTML are modern technologies that go hand in hand. React JS allows you to create reusable codes when you combine it with HTML. React JS also leverages downward data flow. Hence, when you change the states of child structures, it won’t affect the parent structure.
When updating an object, developers manipulate their state and make the required changes. In this case, updates are only applied to the relevant components. Such a data binding approach ensures code stability and consistent app performance.
-
Cost-effective
React JS is a comprehensive library and NOT a framework. This library is consistently combined and used with other JavaScript libraries. And thus, it has a short learning curve as compared to other comprehensive ones. With React, enterprises will be able to streamline app development pipelines without spending too much on their current system.
-
SEO-friendly
Content comes first. Nowadays, developers have to face numerous challenges to make sure their modern applications are SEO-friendly. This is even more crucial when there is ever-growing competition in the market with loads of apps out there, all striving to be the best one.
React JS makes sure your application is SEO-friendly as it is able to mitigate typical search engine failures to read highly-loaded, large JavaScript apps.
Why Choosing React JS for Your Next Project is a Good Idea?
There are many open-source libraries out there to simplify the whole process of front-end web application development. Then, why use React JS?
With rapidly evolving technologies and frameworks, it gets difficult for the software team to invest time and learn new frameworks thoroughly. And, there’s no use in doing so if the framework could eventually lead nowhere.
Here’s why React JS is perfect for your next project:
- User-friendly: React JS is comparatively easier to grasp. The use of simple JavaScript, a reusable component-based approach and a precise supply chain makes React easier to grasp and build applications with. React JS leverages JSX- a syntax deliberately developed for React that lets you combine HTML with JavaScript to simplify app development. Though it is not necessary for developers to use it, they can still write code solely in JavaScript as well.
- Doesn’t need expertise: Anyone with primary-level programming knowledge can grasp React. Languages such as Angular and Ember have higher levels of abstraction and are often addressed as “domain-specific languages” which signify that they demand a longer learning curve. But when opting for React, you simply need a primary understanding of HTML and CSS.
- Native approach: React Native is able to seamlessly build mobile applications. Plus, you can create reusable codes to develop web, Android as well as IOS apps simultaneously.
- Data Binding: React enforces unidirectional data flow. “Flux” is its application architecture that is in charge of directing the data flow towards different components via a single control point known as the dispatcher. Hence, it gets easier to resolve bugs in self-contained components of hefty-sized React apps.
- Testability: Applications built with ReactJS allow effortless testing. React views can act as state functions, and thus you can define the state that goes to the ReactJS view and check the triggered functions, actions, events, and final output.
Conclusion
Pondering over the pros and cons of React JS, we can conclude that React JS is extremely simplified, non-risky yet a robust and comprehensive library. It is highly recommended to utilize React JS to create single page modern applications to boost their intuitiveness, speed and make them user-friendly.
Companies seek reliable ReactJS development services to stay ahead of the competition. To sum it up, the ReactJS library is advanced enough to create large-scale, modern apps. And, it is able to handle data changes over time very well. Try it now!
