do stuff regarding the cancelation request. }); // do other stuff. }); asyncFunction(1, 2).cancel(); ``` #### Compatibility with AbortSignal AbortSignal is a new API from the WHATWG to provide a cancelation mechanism for web APIs. CancelToken can be converted to AbortSignal and the other way around, so they can be used interchangeably. ```js import { CancelToken } from "promise-toolbox"; // From AbortSignal to CancelToken. const cancelToken = CancelToken.fromAbortSignal(signal); // From CancelToken to AbortSignal. const signal = cancelToken.toAbortSignal(); ``` ### Resource management #### Creation ```js import { resource } from "promise-toolbox"; ``` #### Combination ```js import { all, race } from "promise-toolbox"; ``` #### Consumption ```js import { all, race } from "promise-toolbox"; ``` ### Functions ```js import { asyncFn, defer, fromCallback, fromEvent, fromEvents, isPromise, nodeify, pipe, promisify, retry, tryFn, wrapApply, wrapCall } from "promise-toolbox"; ``` #### asyncFn(generator) > Create an async function from a generator. ```js const
