Since the #Moonbit #JavaScript backend post (https://www.moonbitlang.com/blog/js-support) is trending, I thought I'd compare #PureScript backend optimizer (https://github.com/aristanetworks/purescript-backend-optimizer) output to see how it fares. The results were pretty good!

With basically this PureScript code -

run = fromArray  
 >>> flatMapF (fromArray <<< _.members)  
 >>> filterF _.gender  
 >>> mapF (\x -> min 100 (x.score + 5))  
 >>> mapF grade  
 >>> filterF (_ == 'A')  
 >>> foldF (\_ x -> x+1) 0  

the benchmark results are as follows. PureScript is roughly 6x faster than plain JS, and 6x slower than Moonbit output ( -

halfbit_, 8 months ago to cpp

#moonbit seems like another #programminglanguage worth keeping a eye on. I am still hoping for a more sane #cpp successor than #rust, and I’m sad that because rust gets all the hype, great languages like #nim don’t get the love they deserve. https://moonbitlang.com/blog/first-announce/
