I already did .
I have now this
~~~
module.exports = function getShortMessages(messages) {
function smallerfifty(element) {
return element.message.length < 50;
}
return messages.filter(smallerfifty)
}
~~~
and this output :
~~~
[ { message: 'Eiusmod adipisicing esse labore magna elit irure.' },
{ message: 'Amet esse excepteur mollit excepteur.' },
]
~~~
where it schould be
~~~
[ message: 'Eiusmod adipisicing esse labore magna elit irure.' ,
message: 'Amet esse excepteur mollit excepteur.' ,
~~~
