Stupid Question About Isolates

[Richard Eng]

I expect isolates to perform extremely well in the Dart VM, but how well do they perform in the generated JS output? JS is not good at concurrency, even in Node.

[Peter Ahé]

When compiling to JavaScript, we use Workers if they're available. Which I think they are on all supported browsers. The Try Dart site (https://try.dartlang.org/) is compiled to JavaScript and uses Isolate.spawnUri to create a concurrent isolate for compiling so the UI isn't blocked during compilation.

Cheers,
Peter
