### JS
Many of our components require the use of JavaScript to function. Specifically, they require [jQuery](https://jquery.com/), [Popper.js](https://popper.js.org/), and our own JavaScript plugins. Place the following `<script>`s near the end of your pages, right before the closing `</body>` tag, to enable them. jQuery must come first, then Popper.js, and then our JavaScript plugins.

#### Bundle
Include everything you need in one script with our bundle. Our `bootstrap.bundle.js` and `bootstrap.bundle.min.js` include [Popper](https://popper.js.org/), but not [jQuery](https://jquery.com/). For more information about what's included in Bootstrap, please see our [contents]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/contents/#precompiled-bootstrap) section.
