this appears to give me a Uncaught TypeError: Cannot read property 'toUpperCase'... but I imagined it might deal with the error in a similar way to Promises
For this example the following would be better if you weren't sure if some fields would be available
constdata=[{wrongName:'Jason',level:7,cool:true},{wrongName:'Blanche',level:8,cool:false}]Maybe(data).map(people=>people.filter(person=>person.cool)).chain(head).chain(get(['name'])).map(name=>name.toUpperCase()).cata({Just:data=>console.log(data),// JASONNothing:()=>console.log('No data available')})
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()
This looks a excellent library; looking forward to using this. Could you help with the following example?

It seems to looks better with Ramda, isn't it:
PS: thanks a lot for the article

You are totally right. Sorry for my mistake.
