Which of the following statements is not true of jQuery?

jQuery is a versatile and widely-used JavaScript library primarily designed for client-side scripting. It enhances the functionality of JavaScript by making it simpler to perform tasks such as DOM manipulation, event handling, and AJAX interactions.

The first choice highlights jQuery's ability to provide a fast and concise way to perform JavaScript operations, which is a key advantage of using the library. The second option emphasizes its capabilities in simplifying HTML document traversal and manipulation, allowing developers to interact with the structure of web pages more easily. Similarly, the fourth option points out jQuery's proficiency in enabling event handling, making it easier to manage user interactions and apply behavior to web elements.

In contrast, the statement regarding jQuery focusing on server-side scripting is misleading. jQuery operates on the client side, where it enhances user experience through direct interaction with HTML/CSS. Server-side scripting typically involves languages like Node.js, PHP, or Python, which are used to interact with databases and handle requests on the server. Thus, the assertion that jQuery is focused on server-side scripting is not true, as it is fundamentally intended for client-side development.
