Types
abortController
A controller object that allows you to abort one or more DOM requests as and when desired. See AbortController on MDN
type abortController = {signal: abortSignal}Record fields
Module
There are methods and helpers defined in AbortController .
abortSignal
A signal object that allows you to communicate with a DOM request (such as a Fetch) and abort it if required via an AbortController object. See AbortSignal on MDN
type abortSignal = {aborted: bool, reason: JSON.t}Record fields
aborted
Returns true if this AbortSignal's AbortController has signaled to abort, and false otherwise. Read more on MDN
Module
There are methods and helpers defined in AbortSignal .
addEventListenerOptions
type addEventListenerOptions = { mutable capture?: bool, mutable passive?: bool, mutable once?: bool, mutable signal?: abortSignal,}Record fields

event
An event which takes place in the DOM. See Event on MDN
type event = { type_: eventType, target: Null.t<eventTarget>, currentTarget: Null.t<eventTarget>, eventPhase: int, bubbles: bool, cancelable: bool, defaultPrevented: bool, composed: bool, isTrusted: bool, timeStamp: float,}Record fields
type_
Returns the type of event, e.g. "click", "hashchange", or "submit". Read more on MDN
target
Returns the object to which event is dispatched (its target). Read more on MDN
currentTarget
Returns the object whose event listener's callback is currently being invoked. Read more on MDN
eventPhase
Returns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE. Read more on MDN
bubbles
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. Read more on MDN
cancelable
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. Read more on MDN
defaultPrevented
Returns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise. Read more on MDN
composed
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. Read more on MDN
isTrusted
Returns true if event was dispatched by the user agent, and false otherwise. Read more on MDN
timeStamp
Returns the event's timestamp as the number of milliseconds measured relative to the time origin. Read more on MDN

eventTarget
EventTarget is a DOM interface implemented by objects that can receive events and may have listeners for them. See EventTarget on MDN
