Nested grouping of arrays

nest.js

A multi-level groupBy for arrays inspired by D3's nest operator.

Nesting allows elements in an array to be grouped into a hierarchical tree structure; think of it like the GROUP BY operator in SQL, except you can have multiple levels of grouping, and the resulting output is a tree rather than a flat table. The levels in the tree are specified by key functions.

See this fiddle for live demo.

Bare minimum Chrome extension to inject a JS file into the given page when you click on the browser action icon. The script then inserts a new div into the DOM.
// this is the background code...
// listen for our browerAction to be clicked
chrome.browserAction.onClicked.addListener(function (tab) {
// for the current tab, inject the "inject.js" file & execute it
chrome.tabs.executeScript(tab.ib, {
file: 'inject.js'
});
});

Mac OS X setup

Setup Mac OS X

I've done the same process every couple years since 2013 (Mountain Lion, Mavericks, High Sierra, Catalina) and I updated the Gist each time I've done it.

I kinda regret for not using something like Boxen (or anything similar) to automate the process, but TBH I only actually needed to these steps once every couple years...

This code gives the HTML canvas element JavaScript support for letter spacing. Don't confuse letter spacing with kerning http://en.wikipedia.org/wiki/Kerning This code is basically from http://stackoverflow.com/a/15509006
(function(){
var _fillText,
__slice = [].slice;
_fillText = CanvasRenderingContext2D.prototype.fillText;
CanvasRenderingContext2D.prototype.fillText = function() {
var args, offset, previousLetter, str, x, y,
_this = this;
