I wrote a simple curry function in JavaScript which works correctly for most cases:    const add = curry((a, b, c) => a + b + c);  const add2 = add(2);  const add5 = add2(3);  console.log(add5(5)); <script> const curried = Symbol("curr...

I'd like to understand the original meaning of functional reactive programming in Haskell and how it differs from the actual application of FRP in Javascript. Unfortunately, I have only a superficial understanding of Haskell and have to stick wit...

Let's say I want to combine a bunch of Javascript and Julius file. I do it like this:  jsWidget :: Widget jsWidget = do            addScript $ StaticR js_test1_js            toWidget $(juliusFile "static/js/gis/sample.julius")...
I know that Javascript's promises are technically neither functors nor monads in the sense of Haskell, because (among other things)   they include a bind operation that falls back to map when a pure function is passed in (and thus has an ambiguou...
I am fairly new to Haskell. Recently, I heard about this compiler called GHCJs where you can write code in Haskell which can then be compiled to Javascript.   I am interested in using libraries such as three.js and webgl for making cool interactive 3...
I have a simple yesod form:  aYesodForm :: Form Text aYesodForm = renderDivs $ id     <$> areq hiddenField "" Nothing   It generates roughly:  <input type="hidden" id="h2" name="f2" value="">   I wa...
I asked a question before about using lazy evaluation in Scala. I was trying to write the following Haskell function in Scala:  fib a b = c : (fib b c)    where c = a+b   The answer to that question was that I couldn't use Lists, but should rathe...
Haskell has a takeWhile function:  Prelude> takeWhile odd [1,3,5,7,8,9] [1,3,5,7]   It “takes” elements from a list as long as applying the predicate function results in True. At the point it becomes False, it stops.  How can we implement it?...
