EventTarget
Baseline
Widely available
*
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
* Some parts of this feature may have varying levels of support.
The EventTarget interface is implemented by objects that can receive events and may have listeners for them.
In other words, any target of events implements the methods associated with this interface.
Element, and its children, as well as Document and Window, are the most common event targets,
but other objects can be event targets, too.
For example IDBRequest, AudioNode, and AudioContext are also event targets.
Many event targets (including elements, documents, and windows) also support registering event handlers via onevent properties and attributes.
