Articles like this, about up-and-coming features in JavaScript, usually make me think two things: 1) JavaScript is starting to become a "big" language, in terms of number of keywords and syntax; 2) While many of these things that JavaScript is (finally) gaining are things we're familiar with in other languages (and have empirically found to be useful), they often seem somewhat more unwieldy, fiddly, and complicated in JavaScript. As a handwavy example, Ruby generally has most of the stuff these sorts of articles describe, and it can be complicated at times, but usually (in my experience) only when you're trying to do something complicated anyway; in JavaScript, a lot of it looks quite complicated out of the box even when you're doing something that ought to be simple. There are many JavaScript developers out there, some with years of experience, who are confused about, say, `var Foo = function() {}` versus `function Foo() {}`, or the difference between `new Foo()` and `Object.create(Foo.prototype)`. To be honest, it slightly worries me that even more complexity is being added at this point.
