import { ExecutionContext } from "https://deno.land/x/pptr@1.2.0/src/ExecutionContext.ts";
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.
