v8.PromiseHooks

createHook: (callbacks: HookCallbacks) => Function
Registers functions to be called for different lifetime events of each promise. The callbacks init()/before()/after()/settled() are called for the respective events during a promise's lifetime. All callbacks are optional. For example, if only promise creation needs to be tracked, then only the init callback needs to be passed. The hook callbacks must be plain functions. Providing async functions will throw as it would produce an infinite microtask loop.
onAfter: (after: After) => Function
The after hook must be a plain function. Providing an async function will throw as it would produce an infinite microtask loop.
onBefore: (before: Before) => Function
The before hook must be a plain function. Providing an async function will throw as it would produce an infinite microtask loop.
onInit: (init: Init) => Function
The init hook must be a plain function. Providing an async function will throw as it would produce an infinite microtask loop.
onSettled: (settled: Settled) => Function
The settled hook must be a plain function. Providing an async function will throw as it would produce an infinite microtask loop.
