# Composable effects

This is an experiment with composable effects and effectful programs.  It's basically algebraic effects and handlers, using generators as the underlying implementation of continuations.

## Try it

`node -r @babel/register ./examples/delay`

`node -r @babel/register ./examples/async-problem/index ./examples/async-problem/input`

Check out [more examples](examples)

## Highlights

* Separation of effect interfaces and implementations: program with interfaces, supply effect implementations when running programs.

* Composable effects: create new effects from existing ones.

* Composable _programs_: `yield *` can be used to compose effectful programs.

* Asynchronous effects with cancelation.
