React Developer Tools is an essential extension for any developer working with the React library. This tool, available for browsers like Chrome and Firefox, allows developers to inspect the React component hierarchies in the Chrome Developer Tools. Originally developed by Facebook, it has become an indispensable part of the modern React development workflow.
