`Protected` _subscribe

_subscribe(emitter, event, cb, subscriptionHandler?): void
Start listening to events of a certain type emitted by an object. The callback will be called with the chip as this. Works by default for both NodeJS- and DOM-style events. If you are interfacing with a different event system, you can provide a subscriptionHandler that knows how to handle it.
Parameters
- emitter: object
- event: string
- cb: ((...args) => void)
  - - (...args): void
    - Parameters
      Rest ...args: any[]
      Returns void
- Optional subscriptionHandler: SubscriptionHandler
Returns void
Inherited from ChipBase._subscribe
- Defined in src/chip.ts:340

`Protected` _subscribeOnce

_subscribeOnce(emitter, event, cb, subscriptionHandler?): void
Listen to a single event emitted by an object, then stop. The callback will be called with the chip as this. Works by default for both NodeJS- and DOM-style events. If you are interfacing with a different event system, you can provide a subscriptionHandler that knows how to handle them.
Parameters
- emitter: object
- event: string
- cb: ((...args) => void)
  - - (...args): void
    - Parameters
      Rest ...args: any[]
      Returns void
