It would be rad if it's possible for creators of libs to create a namespace for their events, it's well used in jQuery for example in Bootstrap.

Bootstrap Modal emit show.bs.modal event, it's allow user to be sure the show event come from the Bootstrap Modal and not an other lib or a general show event.

Currently, except jQuery I don't know an other libs which handle event namespace

See:

• https://api.jquery.com/event.namespace/
• https://getbootstrap.com/docs/4.1/components/modal/#events
• https://github.com/twbs/bootstrap/blob/v4-dev/js/src/modal.js#L47-L51
