Provide a way to get worker initialization error synchronously

What is the problem this feature will solve?

I'm using a worker to run asynchronous tasks and block the main thread with Atomics.wait().
If the worker has something like syntax errors, it seems that we can only get it by add a listener to error event, the program just hangs since worker can not wake the main thread.

new (require('worker_threads').Worker)(new URL('data:text/javascript,throw new Error'));

What is the feature you are proposing to solve the problem?

Provide a way to get the worker initialization error synchronously.

What alternatives have you considered?

I tried to pass a timeout to Atomics.wait(), but It's just a random magic number because I don't know how long the worker script takes to init.

Commencez par l’initialisation de worker_threads Worker et le comportement de error-event, en utilisant la data URL avec une erreur de syntaxe comme reproduction. Vérifiez comment Atomics.wait() interagit avec le démarrage du worker, puis définissez et testez à quoi devrait ressembler un échec d’initialisation synchrone sans dépendre d’un timeout.
