Async Map and Fold in JavaScript
My latest experiment is an implementation of asynchronous/parallel "map" (and other array functions) in JavaScript and Oni. Oni is a "structured concurrency language" embedded in JavaScript. For my source code and commentary, see oni-map at GitHub. You can leave comments at GitHub too.
All this time reading Real World Haskell must really have warped my brain if a simple testing framework for a JavaScript program has got me thinking about higher-order functions and concurrency semantics...
