Need to modify the number of items during a map in #JavaScript? Use flatMap, which was introduced in ES10! 🔥 #dev #development #code

@devcastcode ES10? I thought we were still on ES6 😢

@devcastcode Is it still a map operation though?

@devcastcode Does a generic flattern exist though?

@devcastcode People love Haskell, they just don't know it yet 😄

@devcastcode I see a monoid in the category of endofunctors here hidden somewhere CC @r_casetta

@devcastcode This is way neat...

@devcastcode Should I see observable in JS? 😆

@devcastcode What could be the real life scenario where we can use this? Just curious

@devcastcode I love JavaScript but this new ES10 doesn’t seem so impressive so far, or maybe im missing something

@devcastcode Or reduce?
