| - Is [scala.js](https://www.scala-js.org/) supported? | ||
| - Should you be able to block a thread waiting for the result of a task? This is really convenient for tests, but it isn't really compatible with a JavaScript runtime and therefore is an issue for [scala.js](https://www.scala-js.org/). | ||

| For some use-cases, a very simple `IO` is the best answer, as it avoids a lot of the overhead and complexity of other solutions. However, other use-cases require low-level concurrency control with asynchrony, resource management, and stack-safety. Considering all of the competing concerns, Cats has opted to not implement its own `IO`/`Task` types and instead encourage users to use a separate library that best serves their use-case. |

an alternate approach is use Free and specify the things you need to do, then finally interpret those into Xor, Try or Future at the end of the world. I think this is a good approach too because generally the IO winds up being kind of an Any side-effect when most times you have a pretty narrow scope.
We already have some nice Free docs to point to, right?

@johnynek good point. I'll add a note about Free and point to the free docs.

I'd be particularly interested in reviews from @mpilquist and @alexandru. Please let me know if there's any way that I can improve the descriptions of Monix and fs2 Tasks.
