Discussion on: Basic monads in Javascript

It seems to looks better with Ramda, isn't it:

const data = [
  { wrongName: 'Jason', level: 7, cool: true },
  { wrongName: 'Blanche', level: 8, cool: false }
];

Maybe(data)
  .map(filter(propEq('cool', true)))
  .map(head)
  .map(prop('name'))
  .map(toUpper)
  .cata({
    Just: console.log
    Nothing: () => console.log('No data available')
  })

PS: thanks a lot for the article

This isn't exactly the same because Ramdas prop() does not return a Maybe, so if that prop did not exist then ramda would return an undefined, which will cause problems down the line. Same with head()

You are totally right. Sorry for my mistake.
