web Worker API suggestion

[Andre Venancio]

Hi Patrick.
Been having a look at that option too, however a linter wouldnt easily
parse that in order to validate my javascript.. I do understand your point,
however makes me feel dirty having to include a task for copying static
file around from my SRC to my DIST folders. would be easier if there was a
way of accessing another memory thread without having to handle this
external file requirement.

Hey Andre!
The issue with this is that it would not be obvious that you are unable to
pass objects from the current scope into the worker (which would break the
entire purpose of having a fast codepath in another thread). You *can* construct
one from a string, however. You just need to wrap it up like a file

Hi,
Not sure this is the best email to contact you guys regarding an API
I've been thinking about this for a while now, and I think it would be
beneficial to update the Worker api to allow you to pass a IIFI function
instead of a external file?
const worker = new Worker('lame.js');
worker.onmessage = (e) => {
console.log(e);
};
// lame.js
this.addEventListener('message', (e) => {
this.postMessage({ message: 'hello back' });
});
to
const worker = new Worker(() => {
this.addEventListener('message', (e) => {
this.postMessage({ message: 'hello back' });
});
});
worker.onmessage = (e) => {
console.log(e);
};
Wouldn't this be better?
Thanks
Andre

At BlinkOn 9 there was discussion of how ergonomics of the Worker API could
be improved in ways similar to what you suggest. Video of that session is
