The new JavaScript Libraries guide discusses JavaScript library files and how they can be used to improve the performance of Web pages.

In the UIZE JavaScript Framework, JavaScript libraries are bundles of JavaScript Modules. Think of a JavaScript module as like a book, where the various methods and properties of the module make up the "pages" of the book. A library is a collection of books. So, in this metaphor, a JavaScript library file is a collection of JavaScript modules, bundled together into a single file. JavaScript libraries offer a performance benefit for pages, by reducing the number of HTTP requests needed in order for the page to have all the JavaScript modules it needs - especially important for pages with rich client interactivity that may use dozens of different modules.
