JavaScriptExecutor is one of the interfaces in selenium. The basic advantage of JavaScriptExecutor is it provides a way to execute JavaScript in Selenium Webdriver. Sometimes locators may not work, in that case JavaScriptExecutor will helps to interact with the web elements on the particular webpage. The reason behind this is; even selenium webdriver internally converts language bindings into its equivalent JavaScript and injects into the respective browser. JavaScriptExecutor is also very useful to identify and interact with the hidden and disabled elements on the web page.
