JavaScript is a popular programming language used to add interactivity and dynamic content to web pages. It allows developers to create complex and engaging user experiences. To ensure that JavaScript is running correctly, it is sometimes necessary to check if it is enabled or active in a web browser.
There are several methods to check if JavaScript is running in a web browser. One common approach is to use the window.alert() function. This function displays a pop-up message with a specified text. If the message appears when the function is called, it indicates that JavaScript is running in the browser.
