Description

This is a feature suggestion.

Workers accept an optional name which can be used for debugging, e.g. in DevTools we show the name in the Sources panel. Screen Shot 2020-09-15 at 10 55 05 am Screen Shot 2020-09-15 at 10 55 12 am

The name is also available to the worker via globalThis.name.

My suggestion is that in src/library_pthread.js, in allocateUnusedWorker when we call new Worker(), we give a useful name like pthread #1 etc. Right now threads just show up with the file name (which also means all the threads have the same name).

Contributor guide

Research direction
Locate the allocateUnusedWorker function in src/library pthread.js and add a name parameter to the new Worker() call using the worker index.
