What syntax is this? Is it a es6 syntax?

I found this syntax when I read someone's source code of vue ui component.

I guess this might be new es6 syntax but I cannot find the definition from any online es6 resources.

Could anybody enlighten me on that?

Here are some code snippets

var _moment = require('moment');
var _moment2 = _interopRequireDefault(_moment);
this.checked.currentMoment = (0, _moment2.default)();

The syntax I cannot understand is (0, _moment2.default).

Looks like regular functions and variables too me ? – adeneo Nov 07 '16 at 14:12

This is "Normal" syntax. I have no clue what the point of the `(0,` is, though. – Cerbrus Nov 07 '16 at 14:13
Which part of the syntax are you asking about? Because all of this is normal JS. `require` is presumably AMD while the `(0, something)` is also "normal", if a bit strange. – VLAZ Nov 07 '16 at 14:17

@FrançoisWahl: That's not how "passing parameters" works. – Cerbrus Nov 07 '16 at 14:17
@Marc It seems as if [this](http://stackoverflow.com/q/19535601/5647260) offers better explanation. – Andrew Li Nov 07 '16 at 14:21

This is in order to perform an indirect call, see – Benjamin Gruenbaum Nov 07 '16 at 14:22

@Cerbrus you are right, when I played with it in jsFiddle It didn't do what I thought..removed false explanation. Cheers :) – Nope Nov 07 '16 at 14:23
@AndrewLi removed my comment, this was just the first entry I found within 3 seconds of googling ;) – Marc Nov 07 '16 at 14:24
This is the output from Babel. It likely once was ES6+ code and has been transpiled to this ES5 code – Charlie Martin Nov 07 '16 at 15:29
