HTML Standard defines WindowOrWorkerGlobalScope

interface mixin WindowOrWorkerGlobalScope {
  [Replaceable] readonly attribute USVString origin;
  readonly attribute boolean isSecureContext;
  readonly attribute boolean crossOriginIsolated;

  undefined reportError(any e);

  // base64 utility methods
  DOMString btoa(DOMString data);
  ByteString atob(DOMString data);

  // timers
  long setTimeout(TimerHandler handler, optional long timeout = 0, any... arguments);
  undefined clearTimeout(optional long id = 0);
  long setInterval(TimerHandler handler, optional long timeout = 0, any... arguments);
  undefined clearInterval(optional long id = 0);

  // microtask queuing
  undefined queueMicrotask(VoidFunction callback);

  // ImageBitmap
  Promise<ImageBitmap> createImageBitmap(ImageBitmapSource image, optional ImageBitmapOptions options = {});
  Promise<ImageBitmap> createImageBitmap(ImageBitmapSource image, long sx, long sy, long sw, long sh, optional ImageBitmapOptions options = {});

  // structured cloning
  any structuredClone(any value, optional StructuredSerializeOptions options = {});
};

This interface mixin is extended in the following specifications:

• Fetch Standard

  
  
  partial interface mixin WindowOrWorkerGlobalScope {
    [NewObject] Promise<Response> fetch(RequestInfo input, optional RequestInit init = {});
  };

• Prioritized Task Scheduling

  
  
  partial interface mixin WindowOrWorkerGlobalScope {
    [Replaceable] readonly attribute Scheduler scheduler;
  };

• High Resolution Time

  
  
  partial interface mixin WindowOrWorkerGlobalScope {
    [Replaceable] readonly attribute Performance performance;
  };

• Indexed Database API 3.0

  
  
  partial interface mixin WindowOrWorkerGlobalScope {
    [SameObject] readonly attribute IDBFactory indexedDB;
  };

• Service Workers Nightly

  
  
  partial interface mixin WindowOrWorkerGlobalScope {
    [SecureContext, SameObject] readonly attribute CacheStorage caches;
  };

• Trusted Types

  
  
  partial interface mixin WindowOrWorkerGlobalScope {
    readonly attribute TrustedTypePolicyFactory trustedTypes;
  };

• Web Cryptography API

  partial interface mixin WindowOrWorkerGlobalScope {
    [SameObject] readonly attribute Crypto crypto;
  };

interface mixin WindowOrWorkerGlobalScope {
  [Replaceable] readonly attribute USVString origin;
