 Methods
addEventListener  
- addEventListener<K extends keyof AnimationEventMap>(
 type: K,
 listener: (this: Animation, ev: AnimationEventMap[K]) => any,
 options?: boolean | AddEventListenerOptions,
 ): void
- Appends an event listener for events whose type attribute value is type. The callback argument sets the callback that will be invoked when the event is dispatched. - The options argument sets listener-specific options. For compatibility this can be a boolean, in which case the method behaves exactly as if the value was specified as options's capture. - When set to true, options's capture prevents callback from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE. When false (or not present), callback will not be invoked when event's eventPhase attribute value is CAPTURING_PHASE. Either way, callback will be invoked if event's eventPhase attribute value is AT_TARGET. - When set to true, options's passive indicates that the callback will not cancel the event by invoking preventDefault(). This is used to enable performance optimizations described in § 2.8 Observing event listeners. - When set to true, options's once indicates that the callback will only be invoked once after which the event listener will be removed. - If an AbortSignal is passed for options's signal, then the event listener will be removed when signal is aborted. - The event listener is appended to target's event listener list and is not appended if it has the same type, callback, and capture. - Type Parameters- K extends keyof AnimationEventMap
 - Parameters- type: K
- listener: (this: Animation, ev: AnimationEventMap[K]) => any
- Optionaloptions: boolean | AddEventListenerOptions
 - Returns void

 type: string,

 - Returns void
- removeEventListener(
 type: string,
 listener: EventListenerOrEventListenerObject,
 options?: boolean | EventListenerOptions,
 ): void
- Removes the event listener in target's event listener list with the same type, callback, and options. - Parameters- type: string
