Explain the use of JavaScriptExecutor in Selenium.

JavaScriptExecutor is a powerful interface in Selenium that allows testers to execute JavaScript code directly within the browser from their Selenium scripts. It’s especially useful for handling situations where standard Selenium commands might not work, such as clicking hidden elements, scrolling to specific parts of a web page, or retrieving dynamic page information. Many Selenium course for beginners programs introduce JavaScriptExecutor early because it helps overcome common automation challenges and improves script reliability. By executing custom JavaScript commands, testers gain better control over web applications, making automation smoother and more efficient, particularly for complex and dynamic user interfaces.
