Adds a new handler for the type
event. Any given listener
is added only once per type
and per capture
option value.
If the once
option is true, the listener
is removed after the next time a type
event is dispatched.
The capture
option is not used by Node.js in any functional way other than tracking registered event listeners per the EventTarget
specification.
Specifically, the capture
option is used as part of the key when registering a listener
.
Any individual listener
may be added once with capture = false
, and once with capture = true
.
