The Firefox developer plugin and the Chrome web browser also have React developer tools that let you examine component hierarchies in a simulated DOM. Selecting a component will allow you to verify and update its current status and properties. Suitable for SEO Mainstream JavaScript frameworks have a difficulty with SEO. JavaScript-intensive applications are challenging for search engines to comprehend. Many site developers have voiced their discontent with this issue. This issue is resolved by ReactJS, which makes it simpler for developers to navigate across many search engines. This is true due to the fact that React.js applications can run on the server and the virtual DOM will render and return to the browser as a typical web page. The Major Disadvantages of React js Pace of Development React advances at a quick clip, which may have advantages as well as disadvantages. If there is a drawback, some developers may be reluctant to often learn new skills due to the environment's constant change. The frequent upgrading makes it difficult to absorb and comprehend the changes. They must regularly acquire new skills and keep their existing ones current. Absence of documentation This is just another drawback of rapidly evolving technology. Given the rapid pace of React technology and development, it is challenging to keep up with the documentation. To avoid this, developers record their own instructions when new versions and tools for their ongoing projects are published.

It is a grammar enhancement that enables the blending of JavaScript with HTML. JSX is seen by some in the development community as a hurdle, especially for new developers, despite the benefits of this approach. The developers struggle with the complexity of the learning curve. Focus on the user interface is lacking There are several tools included with React for creating and designing user interfaces. Contrary to frameworks, React JS is not a "all-in-one tool" for app development. As a result, React development is solely in charge of the user interface if you employ a model-view-controller (MVC) architecture. To build the model and run the control system, the developers will need to employ additional tools. To create a successful app, you'll need to employ additional tools to manage other key elements like the data storage and backend.

Unfinished collection of tools Businesses should be aware that React is limited to the UI layer of an application. Everything else pertaining to the web development project is outside of it aside from that. Therefore, even after using React web app development, developers still need to choose a framework to produce a quick, lovely, and appropriate user interface. Because React does not have access to the entire toolkit, developers will struggle to complete the project.
