The Popularity of React JS Development Explained

ReactJS took the tech world by storm with over 220,000+ live websites already using its power. And when you see big names like Netflix, PayPal and Apple hopping on the ReactJS.

What is ReactJS?

ReactJS is a JavaScript library that is created by Facebook. It is an efficient and flexible open-source JavaScript framework for creating simple, quick, and scalable front-ends of web apps.

Why is ReactJS development popular?

1. Developer Toolset

Learning new technology and applying it to real-world tasks can be both entertaining and helpful, but only if done right. Facebook recognizes this, which is why their React JS framework now includes much-needed React dev tools and Chrome dev tools.

These React tools primarily aid every React developer in locating child and parent components, observing component hierarchies, and inspecting the current state and properties of components.

2. Helps in Building Rich Interface

In today's world, the quality of an application's user interface is critical. If the user interface is badly designed, an application's chances of success are reduced. However, if an app has a high-quality user interface, there's a higher likelihood that your consumers will enjoy using it. 

As a result, creating rich user interfaces is almost a need for an app to survive and grow. The good news is that Reacts declarative components enable us to make such high-quality user interfaces.

3. Creates Custom Components

React includes JSX, an optional syntax extension that allows you to create your own components. These components essentially allow HTML language and make all subcomponent rendering a possibility.

JSX has already been used for developing custom components, constructing high-volume apps, and turning HTML mockups into React Element trees.

4. Increases Developers’ Productivity

When an app has complicated logic and a single change in one component could have a significant impact on other components, frequent updates can become very frustrating for developers.  However, Facebook has bolstered React with the component reusability functionality to tackle this issue.

Reacts component reusability allows a React js developer to reuse the same digital objects. And the procedure to do that is quite easy too. For example, developers can start with simple components like buttons, text fields, and checkboxes and work their way up to wrapper components, which are then carried forward to the root component.

Since each component in React has its own internal logic, which is easy to alter, this method essentially enables better code maintenance and growth. Additionally, it increases the app's efficiency.

5. Virtual DOM

When developing a complicated app, it's critical to specify the app's structure from the start because it might affect the app's performance.

To put it another way, the DOM model is a hierarchical representation of an HTML & XML document. As a result, a little change at a higher level layer might have a significant influence on an application's user interface. Facebook has created a virtual DOM functionality to address this issue.

As the name implies, virtual DOM is a virtual representation of DOM that allows developers to test any changes to the virtual DOM first and assess risks associated with each change. As a consequence, this method aids in the maintenance of excellent app performance and ensures a better user experience.

6. Code Stability

React utilizes downward data flow to make sure that modifications to the child structure have no impact on the parent structure.

As a result, anytime developers make changes to an object, all they have to do is edit its states and make the necessary modifications. Only a single component will be changed in this manner.

As a result of this data flow and structure, the application's code is more stable and runs more smoothly.

7. Easy Testing

One of the things that make React arguably the best is how easy it is to test React-based projects. This is because views are considered as functions of a certain state in React. As a result, React developers and testing engineers can work closely together to change any states that are passed over React View.

The development team has complete control over the code's output, including all functions, events, & actions. Then they can quickly determine whether the app is performing as planned and, if not, select the area to focus on.

8. SEO-Friendly

One of the most well-known aspects of React is its ability to make use of SEO benefits. By implementing React, businesses can substantially reduce website load speeds and begin ranking higher in search engines. It's all due to Reacts emphasis on rendering speed.

Since React allows you to use the same code for both the client and server sides of web apps, you can save time and money. This means that any website that uses React has an instant performance advantage, making it more appealing to both users and crawlers.
