Re: ES6 for beginners, part 3
#2Perhaps I'm odd, but I'm not going to go past ES5. ES5 feels like the last version of the JavaScript language that is true to itself ("As in, pure WAT?" No, I mean not huge).
When I want more capabilities, I will select from the many wonderful compile-to-JS languages that are a genuine departure.

#3Array.prototype.map()[1] has been in js since ES5. Likewise with filter[2] and reduce[3]...

Out of all the languages I've been using lately, I actually like the direction JavaScript has been going.
Swift started off cool as a kind of Objective-C with less C cruft and more Haskell type expressiveness, but started turning into C++.
Clojure started off fast adding destructuring within 3 versions, but hasn't really done anything cool since then, whereas JS picked up destructuring but kept going.
Ruby started focusing on optional typing but JS left that up to TypeScript which seemed like a better way of going about it.
Python 3 has just been a mess from my perspective. I still can't figure out why after all this time they haven't added anonymous functions without having to give it a name (lambdas don't count, they can only have expressions).
Go continues to be the hipster language that says copy/pasting is fine, and that if you have a problem with it then go write a script that generates code, not learning any lessons from Java.
Java 8 adds nice FP functionality but it feels very unidiomatically tacked on and doesn't fit into the rest of the Java stdlib very well (e.g. how Optional isn't meant to be used directly pretty much ever).
JavaScript keeps adding more features that I liked from all the above languages and then some. My main gripe about JS is the unfortunate confusing naming scheme situation.

Well, JavaScript slowed down after ES2015 too.
On the other hand, the module system really takes time and async/await was one big step.

I'm not a fan of kitchen-sink approach for ES6+ features, but honestly at this point I can't do without const/let and arrow functions (and to a lesser degree destructuring assignment and template literals).

Don't forget PHP!
Despite it's reputation, it's gotten quite a large speed boost, a lot of new features (like typing!), And a lot more!
It's shooting to be what Java always felt like it should have been in my eyes.
Re: ES6 for beginners, part 3
#8I have kind of a tangential question. I have done back-end development, mostly with Python and Django. I know some basic HTML, CSS, and JavaScript but not much. A couple of years ago, when I started dabbling in web development, those were much smaller and less complex. You could go through a couple of resources (JavaScript: The Good Parts, jQuery documentations, etc.) and learn everything there was that you needed to know. Now, they have grown exponentially in complexity and scope, and there are so many choices and paradigms that I don't even know how to start.
For someone who has done back-end development, but is now trying to steer his career into front-end development, what resources would you suggest? What do I need to know, and which books and documentations do I need to read, before I can claim I am a front-end developer?
(I will be basically starting from zero. I cannot use the resources that build up on previous knowledge and assume you know everything that came before)

I've looked into modern PHP for a new potential job, and it looks like it adopted a lot of Java features in the past few years. But one thing that really unsettles me is that anonymous functions need the `use` keyword to manually capture variables from lexical scope, which seems completely stupid and I don't know why they went that route instead of inferring this data from -- wait for it... -- lexical scope.

I disagree!
After ES2015 includes:
* Async/await
* a bunch of destructuring with the rest and spread operators
* More class "nice to haves" like static properties and possibly more soon
* Async iteration
* Shared memory and atomics (which I'm not all that happy about, but many people are)
And going even further "in the future" it might have stuff like:
* Decorators (of they can ever settle on it!)
* Observables
* Defensible classes (again, not really happy with this, but what can ya do!)
* Function bind syntax
* Some "collection" nice to haves
And more.
JS isn't going to be slowing down any time soon!
