13.2.5.55 DOCTYPE name state

EOF
Emit that DOCTYPE token

Change to "Emit the current DOCTYPE token" to match the style of the rest of the doc.

I know this is specific to web workers, however I think this could be adapted to work for service workers. I was looking to create a separate plugin but the code would be mostly the same.

Looks like it scans the AST for a keyword (Worker) and generates an entry for the referenced file.

// web worker
new Worker('./foo.js', { type: 'module' })

// service worker
navigator.servi

Problem

Synchronous calls are blocking the even loop leading to performance degradation:

The synchronous form blocks the Node.js event loop and further JavaScript execution until the operation is complete.
