An event which takes place in the DOM.
bubbles: boolean
      
    Returns true or false depending on how event was initialized. True if event goes through its target's ancestors in reverse tree order, and false otherwise.
cancelBubble: boolean
      
    
cancelable: boolean
      
    Returns true or false depending on how event was initialized. Its return value does not always carry meaning, but true can indicate that part of the operation during which event was dispatched, can be canceled by invoking the preventDefault() method.
composed: boolean
      
    Returns true or false depending on how event was initialized. True if event invokes listeners past a ShadowRoot node that is the root of its target, and false otherwise.
currentTarget: EventTarget | null
      
    Returns the object whose event listener's callback is currently being invoked.
defaultPrevented: boolean
      
    Returns true if preventDefault() was invoked successfully to indicate cancellation, and false otherwise.
eventPhase: number
      
    Returns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.
isTrusted: boolean
      
    Returns true if event was dispatched by the user agent, and false otherwise.
returnValue: boolean
      
    
srcElement: EventTarget | null
      
    
target: EventTarget | null
      
    Returns the object to which event is dispatched (its target).
timeStamp: number
      
    Returns the event's timestamp as the number of milliseconds measured relative to the time origin.
type: string
      
    Returns the type of event, e.g. "click", "hashchange", or "submit".
NONE: 0
      
    
CAPTURING_PHASE: 1
      
    
AT_TARGET: 2
      
    
BUBBLING_PHASE: 3
      
    
composedPath(): EventTarget[]
      
    Returns the invocation target objects of event's path (objects on which listeners will be invoked), except for any nodes in shadow trees of which the shadow root's mode is "closed" that are not reachable from event's currentTarget.
initEvent(type: string,bubbles?: boolean,cancelable?: boolean,): void
      
    
preventDefault(): void
      
    If invoked when the cancelable attribute value is true, and while executing a listener for the event with passive set to false, signals to the operation that caused event to be dispatched that it needs to be canceled.
stopImmediatePropagation(): void
      
    Invoking this method prevents event from reaching any registered event listeners after the current one finishes running and, when dispatched in a tree, also prevents event from reaching any other objects.
stopPropagation(): void
      
    When dispatched in a tree, invoking this method prevents event from reaching any objects other than the current object.
