What is the function of JavaScript libraries like jQuery in Dreamweaver?

JavaScript libraries like jQuery play a significant role in web development by simplifying the process of writing JavaScript code. They provide a collection of pre-written, tested, and optimized functions that developers can utilize to perform common tasks, such as DOM manipulation, event handling, and animation effects, with far less effort compared to writing raw JavaScript from scratch.

Utilizing jQuery enables developers to write less code while achieving the same functionality, thus speeding up the development process and reducing the potential for errors. This efficiency is particularly beneficial in a tool like Dreamweaver, where integrating JavaScript into web projects is streamlined, promoting quicker project completions and easier maintenance.

The other options, while relevant to web development, do not accurately reflect the primary purpose of JavaScript libraries like jQuery. Graphic design involves tools for visual layout rather than coding libraries, database management pertains to backend functionalities, and connecting to server applications focuses on server-side processing, which is not the primary function of jQuery.
