Which of the following statements about JavaScript is correct?

The assertion that JavaScript requires a Java-enabled browser to operate is not correct. JavaScript is a separate programming language that does not depend on Java or a Java-enabled environment. Instead, it is executed in the browser's built-in JavaScript engine. This means that once a browser is capable of reading and executing JavaScript, it does not require any additional Java-related framework.

JavaScript is primarily used in web development to create interactive effects within web browsers and is also utilized in server-side development with environments like Node.js. Its versatility allows it to work across various platforms, including both web and mobile applications, making it widely applicable beyond a single domain. In contrast, the other options are misleading regarding the nature and capabilities of JavaScript.

For instance, JavaScript does not only focus on mobile applications; it is vital for web applications and can run on multiple platforms. Additionally, JavaScript is an interpreted language rather than a compiled one, and it does not need any specific Java environment to function. Therefore, it plays a crucial role in modern web development without being restricted to any of the mentioned constraints.
