 - Utility libraries: Provide a bunch of functions to make mundane tasks easier and less boring to manage. [jQuery](https://jquery.com/) for example provides its own fully-featured selectors and DOM manipulation libraries, to allow CSS-selector type selecting of elements in JavaScript and easier DOM building. It is not so important now we have modern features like {{domxref("Document.querySelector()")}}/{{domxref("Document.querySelectorAll()")}}/{{domxref("Node")}} methods available across browsers, but it can still be useful when older browsers need supporting.
 - Convenience libraries: Make difficult things easier to do. For example, the [WebGL API](/en-US/docs/Web/API/WebGL_API) is really complex and challenging to use when you write it directly, so the [Three.js](https://threejs.org/) library (and others) is built on top of WebGL and provides a much easier API for creating common 3D objects, lighting, textures, etc.
   The [Service Worker API](/en-US/docs/Web/API/Service_Worker_API) is also very complex to use, so code libraries have started appearing to make common Service Worker uses-cases much easier to implement (see the [Service Worker Cookbook](https://github.com/mozilla/serviceworker-cookbook) for several useful code samples).
-- Effects libraries: These libraries are designed to allow you to easily add special effects to your websites. This was more useful back when {{glossary("DHTML")}} was a popular buzzword, and implementing an effect involved a lot of complex JavaScript, but these days browsers have a lot of built in CSS3 features and APIs to implementing effects more easily.

 - UI libraries: Provide methods for implementing complex UI features that would otherwise be challenging to implement and get working cross browser, for example [Foundation](https://foundation.zurb.com/), [Bootstrap](https://getbootstrap.com/), and [Material-UI](https://material-ui.com/) (the latter is a set of components for use with the React framework). These tend to be used as the basis of an entire site layout; it is often difficult to drop them in just for one UI feature.
 - Normalization libraries: Give you a simple syntax that allows you to easily complete a task without having to worry about cross browser differences. The library will manipulate appropriate APIs in the background so the functionality will work whatever the browser (in theory). For example, [LocalForage](https://github.com/localForage/localForage) is a library for client-side data storage, which provides a simple syntax for storing and retrieving data. In the background, it uses the best API the browser has available for storing the data, whether that is [IndexedDB](/en-US/docs/Web/API/IndexedDB_API), [Web Storage](/en-US/docs/Web/API/Web_Storage_API), or even WebSQL (which is now deprecated, but is still supported in some older versions of Safari/IE). As another example, jQuery
