 Published for Scala 2.11, 2.12, 2.13, 3. Functionality is fully supported on all platforms supported by Scala.js (including web workers). In the event that a given platform does *not* have the necessary functionality to implement `setImmediate`-style yielding (usually `postMessage` is what is required), the implementation will transparently fall back to using `setTimeout`, which will drastically inhibit performance but remain otherwise functional.
