@kangax's ES6 quiz, explained

@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:

Question 1:

(function(x, f = () => x) {

This is the follow up to a post I wrote recently called From Require.js to Webpack - Party 1 (the why) which was published in my personal blog.

In that post I talked about 3 main reasons for moving from require.js to webpack:

1. Common JS support
2. NPM support
3. a healthy loader/plugin ecosystem.

Here I'll instead talk about some of the technical challenges that we faced during the migration. Despite the clear benefits in developer experience (DX) the setup was fairly difficult and I'd like to cover some of the challanges we faced to make the transition a bit easier.

var fs = require('fs')

var trie = {}
var tempWords = {};

fs.readFile('./text.txt',function(err,callback){
    var str = callback.toString();
    str = str.replace(/[^\u4e00-\u9fa5]/g,'@');
    str = str.replace(/@+/g,' ')
    split(str);

See my DASH-IF presentation from October, 2014:

1. encode multiple bitrates with keyframe alignment:
   ffmpeg -i ~/Movies/5D2_Portrait.MOV -s 1280x720 -c:v libx264 -b:v 1450k -bf 2 \
     -g 90 -sc_threshold 0 -c:a aac -strict experimental -b:a 96k -ar 32000 out.mp4

   My input was 30 fps = 3000 ms. If it were 29.97, then a GOP size of 90 frames will yield a base segment
   size of 3003 milliseconds. You can make the segment size some multiple of this, e.g.: 6006, 9009, 12012.
