Binder

trait Binder[-El <: Base] extends Modifier[El]

Binder is a Modifier that creates a subscription when invoked.

Note, this Modifier is NOT idempotent: Calling it N times will create and bind N subscriptions
onMountBind can take care of this, see the docs

trait Modifier[El]

class Object

trait Matchable

class Any

class EventListener[Ev, Out]

class KeyUpdater[El, K, V]

Value members

This method is used by onMountBind to cancel this subscription on unmount

You can count on this method being a no-op in your libraries and end user code.

The reason this method is not abstract is to avoid broken SAM sugar in case of meta modifiers. See https://github.com/raquo/scala-dom-types/issues/27
