..
AbortController	A utility class used to signal cancelation in selected `Promise`-based APIs. The API is based on the Web API `AbortController`.
AbortSignal	Used to notify observers when `AbortController.abort()` is called.
AddEventListenerOptions	Options for `EventTarget.addEventListener`.
Blob	Encapsulates immutable, raw data that can be safely shared across workers.
BlobPart	A part accepted by the `Blob` / `File` constructors.
BlobPropertyBag	Options for the `Blob` constructor.
BodyInit	Values accepted as request/response bodies.
BroadcastChannel	A channel for broadcasting messages to other contexts listening on the same name.
ByteLengthQueuingStrategy	A queuing strategy that counts the byte length of chunks.
CloseEvent	An event that fires when a `WebSocket` connection closes.
CloseEventInit	Options for the `CloseEvent` constructor.
CompressionStream	A transform stream that performs compression (`deflate`, `deflate-raw`, `gzip`, or `brotli`).
CountQueuingStrategy	A queuing strategy that counts the number of chunks.
CustomEvent	A browser-compatible implementation of `CustomEvent`.
CustomEventInit	Options passed to the `CustomEvent` constructor.
DOMException	The WHATWG `DOMException` class.
DecompressionStream	A transform stream that performs decompression (`deflate`, `deflate-raw`, `gzip`, or `brotli`).
Event	A browser-compatible implementation of the `Event` class.
EventInit	Options passed to the `Event` constructor.
EventListener	An object with a `handleEvent` method, usable as an event listener.
EventListenerOptions	Options for `EventTarget.removeEventListener`.
EventSource	A browser-compatible `EventSource` (Server-Sent Events) implementation.
EventSourceInit	Options for the `EventSource` constructor.
EventTarget	A browser-compatible implementation of the `EventTarget` class.
Fetch	Browser-compatible `fetch()` (undici), exposed as a static on `globalThis`.
File	Provides information about files. Extends `Blob`.
FilePropertyBag	Options for the `File` constructor.
FormData	A browser-compatible `FormData` implementation (undici / fetch).
Headers	HTTP headers for `fetch` / `Request` / `Response` (undici).
Lock	A held lock passed to the `LockManager.request` callback.
LockManager	Web Locks API (`navigator.locks`). Node.js exposes a partial implementation.
LockManagerSnapshot	Result of `LockManager.query()`.
LockOptions	Options for `LockManager.request`.
MessageChannel	Creates a pair of connected `MessagePort` objects.
MessageEvent	Represents a message sent via `MessagePort` / `BroadcastChannel` / `WebSocket`.
MessageEventInit	Options for the `MessageEvent` constructor.
MessagePort	One end of a two-way communication channel created by `MessageChannel`.
MessagePortTransferable	Transferable objects accepted by the web `MessagePort.postMessage` transfer list in Node (matches the practical subset already externed — no invented types).
Navigator	A partial browser-compatible `Navigator` implementation exposed as the `navigator` global in Node.js.
QueuingStrategy	A queuing strategy dictionary used by web stream constructors (`ReadableStream`, `WritableStream`, `TransformStream`, etc.).
ReadableByteStreamController	Controller for a byte-oriented `ReadableStream`.
ReadableStream	A browser-compatible implementation of `ReadableStream`.
ReadableStreamBYOBReader	BYOB reader for a byte-oriented `ReadableStream`.
ReadableStreamBYOBRequest	A pull-into request associated with a `ReadableByteStreamController`.
ReadableStreamDefaultController	Default controller for a `ReadableStream`.
ReadableStreamDefaultReader	Default reader for a `ReadableStream`.
ReadableStreamReadResult	Result of `ReadableStreamDefaultReader.read()` / BYOB `read()`.
