This class represents a context for JavaScript execution. A [Page] might have many execution contexts:

  • each frame has "default" execution context that is always created after frame is attached to DOM. This context is returned by the Frame.executionContext method.
  • Extension's content scripts create additional execution contexts.

Besides pages, execution contexts can be found in workers.
