In ES6, both of these are legal:  var chopper = {     owner: 'Zed',     getOwner: function() { return this.owner; } };   and, as shorthand:  var chopper = {     owner: 'Zed',     getOwner() { return this.owner; } }   Is it possible...
How one can write a function, which takes only few attributes in most-compact way in ES6?  I've came up with solution using destructuring + simplified object literal, but I don't like that list of fields is repeated in the code.  Is there a...
The question is directed at people who have thought about code style in the context of the upcoming ECMAScript 6 (Harmony) and who have already worked with the language.  With () => {} and function () {} we are getting two very similar ways to w...
UPDATE: Recently a brilliant article from Mozilla came up. Read it if you're curious.   As you may know they are planning to include new Symbol primitive type in ECMAScript 6 (not to mention some other crazy stuff). I always thought that the...
I'm sure that this is relatively straightforward and that I'm missing something obvious. I'm reading through Mozilla's tutorials on ES6, and their chapter on destructuring contains the following pattern:     FUNCTION PARAMETER DEFIN...
Given the provided (very simple) generator, is it possible to return the generator back to its original state to use again?  var generator = function*() {     yield 1;     yield 2;     yield 3; };  var iterable = generator();  for (let x of iterable)...
I'm trying to use the new (ES6) Map objects in order to represent a map between properties and a value.  I have objects in a form similar to:   {key1:value1_1,key2:value2_1},..... {key1:value1_N,key2:value2_N}   I want to group them based on both...
For ES6 generators, why does the author of this blog post say:  from: http://davidwalsh.name/es6-generators     "The first next(..) call, we don't send in anything. Why? Because there's no yield expression to receive what we pass in."...
The problem is?  [email protected]:~$ node --harmony test.js  /home/longhao33/test.js:1 (function (exports, require, module, __filename, __dirname) { let str = 'es666666666666';                                                               ^^^...
