var { name: x } = person
Day 1 : that's some good ES6 code man, I'm so 2017
Day 5 : Oh yeah I think it works, dont really remember
Day 17 : WTF is that ? Is that even Javascript ?

Just in case look at destructuring assignement

@AdrienITTS learn about it yesterday! Great little feature!

What's that? Someone can explain?

@pagrette that's equal to var x = person.name
You can do something like :
var { name: x, surname: y, age: z } = person

Ok I see thanks.. but I don't like, it's very not a clear way so source code is not easy to read

@pagrette terrible readability, but better than repeating the code over and over; x = person.name, y = person.age, etc.

It's really not very 2017 if you're still using var... Better to use let or const as appropriate.

Otherwise yeah, little weird looking, but if it's unclear, comment it!

@nmunro yeah true, but wanted to show only one "New thing"

The thing where ES6 starts to confuse is nested higher order arrow functions.

Stuff life this is still useful and readable:

const invert = f => (...a) => !f(...a);

const is = prop => value => obj => obj.hasOwnProperty(prop) && obj[prop] == value;

isCat = is('type')('cat')

So you can do things like animals.filter(invert(isCat))

But eventually people are going to use combinators in js...
f=>((x)=>f((v)=>x(x)(v)))((x)=>f((v)=>x(x)(v)))

Happened every time, last year. Now I never use dat again. Moved to python and their silly indent
