Asynchronous methods and transitions

All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.

[See our JavaScript documentation for more information](/docs/{{ .Site.Params.docs_version }}/getting-started/javascript/#asynchronous-functions-and-transitions).
