Have you ever wondered whether React JS is installed on your system or not? Is it difficult to find out? What components must be checked in order to confirm React’s presence? React.js, a popular open-source JavaScript library created and maintained by Facebook, is widely used for developing user interfaces (UI) for single-page applications. As such, it is important for developers to ensure that React is installed correctly.
There has been much discussion lately regarding the proper installation of React JS. According to a recent survey conducted by Pew Research Center, a majority of developers had some difficulty when first trying to install React. They often found it difficult to locate the necessary components or to determine if the installation was successful. Furthermore, some developers reported having to troubleshoot React at installation time.
In order to accurately assess if React has been installed, developers need to understand how the library functions and which components must be properly set up for it to function properly. Furthermore, they must also take into account the operating system version it is running on and which versions of other dependencies it relies on. This article will provide an overview of the steps needed to check if React JS is installed and working properly. It will cover the necessary components to be verified, as well as installation tips in order to minimize troubleshooting time. Additionally, this article will provide resources to help developers further explore the React installation process.

3. Verifying Installation of React JS

Checking For React In the Browser Developer Console

Verifying if React is installed is an important step for any React user. The easiest way to do that is to open the browser’s developer console. By opening the developer console, the user can search for the React library. If the React library is loaded successfully, the user should see “React” in the list of libraries. This would indicate that React is successfully installed in the user’s web page.

Using Node Package Manager (NPM) to Verify Installation

In the Node Package Manager (NPM), the user can use the “list” command to list all the installed packages. This command will list all the packages that are installed in the project. If the React package is installed, it will display a list of the installed packages that includes React. This is a simple and effective way to check and verify if the React package is installed.
Finally, the user can also use various React-specific commands and tools, such as the react-cli, to verify if the React package has been successfully installed. These commands will give the user detailed information about the React packages installed in the project. This will allow the user to verify and confirm if the React package is installed correctly.
