17 Pro JavaScript tricks you didn't know

Nice article, You can make the pro ones even more pro.

for instance:

const hungry = true;
const eat = hungry ? 'yes' : 'no';

And this one:

const array = [100, 23, 23, 23, 23, 67, 45]; 
const outputArray = new Set(array);

I also find there is a thin line between "pro" and unreadable code in some cases, always keep in mind if something makes the code unreadable just to love a couple symbols.
