Moving to ES6 from CoffeeScript

I fell in love with CoffeeScript a couple of years ago. Javascript has always seemed something of an interesting curiosity to me and I was happy to see the meteoric rise of Node.js, but coming from a background of Python I really preferred a cleaner syntax.

In any fast moving community it is inevitable that things will change, and so today we see a big shift toward ES6, the new version of Javascript. It incorporates a handful of the nicer features from CoffeeScript and is usable today through tools like Babel. Here are some of my thoughts and issues on moving away from CoffeeScript in favor of ES6.

While reading I suggest keeping open a tab to Babel's learning ES6 page. The examples there are great.

Punctuation

Holy punctuation, Batman! Say goodbye to your whitespace and hello to parenthesis, curly braces, and semicolons again. Even with the advanced ES6 syntax you'll find yourself writing a lot more punctuatio

Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus

csv.parse(fs.readFileSync('./csv_with_headers.csv'), function(err, data) {
    // Store the headers row
    var headers = data[0];

    // Remove the headers row
    data.shift();

    var objects = _.map(data, function(csvRow) {

How to make the Webster's 1913 your default Kindle dictionary

1. Download a Kindle-compatible version of the dictionary here. Unzip the .rar archive.

2. Get the "Send to Kindle" program on your computer. Here's the link for the Mac.

3. Right-click your recently downloaded (unzipped) dictionary file, and click the "Send to Kindle" menu item. It will arrive on your Kindle shortly.

4. Once the dictionary has arrived, go to your settings -- on my newish paperwhite, it's at Home > Settings > Device Options > Language and Dictionaries > Dictionaries > English. Choose the Webster's 1913.
