@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) {
// IE | |
// conditional comment | |
(function(dom){ | |
dom.innerHTML = '<!--[if IE]><br><![endif]-->'; | |
return !!dom.firstChild.tagName; | |
})(document.createElement('p')); | |
// Conditional Compilation | |
