Short summary: "Making diagrams with a GUI didn't feel hard enough, so I do it with Haskell instead because Serious Computer Science"
(I'd also suggest that you meant 'recoiled', not 'rebuked')
Would the same expectation be in place of my examples were in JavaScript? I doubt it.
That said, it still would've been nice to hear if Haskell has bought you anything that other languages don't do.
Would I have asked the same question for a JS article? Maybe I wouldn't have asked - I'm a bit more familiar with JS than I'm with Haskell - but a "and here's why I picked those tools" section would still have been interesting. I like hearing how people think about solving problems.
The fate of writing in public: people will always ask for more info on the parts that they're interested in.
