Boilerpipe Text	jQuery API jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. If you're new to jQuery, we recommend that you check out the jQuery Learning Center . If you're updating to a newer version of jQuery, be sure to read the release notes published on our blog . If you're coming from a version prior 1.9, you should check out the 1.9 Upgrade Guide as well. Note that this is the API documentation for jQuery core.

Readable Markdown	## jQuery API jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. If you're new to jQuery, we recommend that you check out the [jQuery Learning Center](https://learn.jquery.com/). If you're updating to a newer version of jQuery, be sure to read the release notes published on [our blog](https://blog.jquery.com/). If you're coming from a version prior 1.9, you should check out the [1\.9 Upgrade Guide](https://jquery.com/upgrade-guide/1.9/) as well. Note that this is the API documentation for jQuery core. Other projects have API docs in other locations: - [jQuery UI API docs](https://api.jqueryui.com/) - [jQuery Mobile API docs](https://api.jquerymobile.com/) - [QUnit API docs](https://api.qunitjs.com/) *** Create a new jQuery object with elements added to the set of matched elements.
