@kangax created a new interesting quiz, this time devoted to ES6 (aka ES2015). I found this quiz very interesting and quite hard (made myself 3 mistakes on first pass).
Here we go with the explanations:
(function(x, f = () => x) {| tweets.csv comes from `twint -u dam_io --csv -o tweets.csv` |

| setTimeout(() => resolve('☕'), 2000); // it takes 2 seconds to make coffee | |

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”
You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?
| // Safari, in Private Browsing Mode, looks like it supports localStorage but all calls to setItem | |
| // throw QuotaExceededError. We're going to detect this and just silently drop any calls to setItem | |
| // to avoid the entire page breaking, without having to do a check at each usage of Storage. | |

I say "animated gif" but in reality I think it's irresponsible to be serving "real" GIF files to people now. You should be serving gfy's, gifv's, webm, mp4s, whatever. They're a fraction of the filesize making it easier for you to deliver high fidelity, full color animation very quickly, especially on bad mobile connections. (But I suppose if you're just doing this for small audiences (like bug reporting), then LICEcap is a good solution).
