## Events
Bootstrap provides custom events for most plugins' unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. `show`) is triggered at the start of an event, and its past participle form (ex. `shown`) is triggered on the completion of an action.
All infinitive events provide [`preventDefault()`](https://developer.mozilla.org/en-US/docs/Web/API/Event/preventDefault) functionality. This provides the ability to stop the execution of an action before it starts.

Each plugin also exposes its raw constructor on a `Constructor` property: `$.fn.popover.Constructor`. If you'd like to get a particular plugin instance, retrieve it directly from an element: `$('[rel="popover"]').data('popover')`.
### Asynchronous functions and transitions
All programmatic API methods are **asynchronous** and returns to the caller once the transition is started but **before it ends**.
In order to execute an action once the transition is complete, you can listen to the corresponding event.

For simple transition effects, include `transition.js` once alongside the other JS files. If you're using the compiled (or minified) `bootstrap.js`, there is no need to include this—it's already there.
All Bootstrap Javascript depend on `util.js` and it has to be included alongside the other JS files. If you're using the compiled (or minified) `bootstrap.js`, there is no need to include this—it's already there.
Transition.js is a basic helper for `transitionEnd` events as well as a CSS transition emulator. It's used by the other plugins to check for CSS transition support and to catch hanging transitions.
