    Read Shape Up by basecamp on a kindle / reMarkable / eReader

Basecamp's new book Shape Up is now available online (https://basecamp.com/shapeup) to read page-by-page.
There is a .pdf version, but that's not the best format for Kindle / other eReaders. Instead, we can convert the page-by-page into an eReader friendly format.
Part 1: Convert to a single page

NOTE: This has only been tested on Chrome

    "Parens and Performance" – counterpost

Kyle Simpson (@getify) wrote a very thoughtful post
decrying optimize-js, which is a tool I wrote that exploits known optimizations
in JavaScript engines to make JS bundles parse faster (especially minified bundles, due to what
could be reasonably described as a bug in Uglify).
Kyle lays out a good case, but I tend to disagree with nearly all his points. So here's my rebuttal.

  
## simple-throttle.js
var isThrottled = false,
    throttleDuration = 24; // ms

function thingToThrottle() {
    if (isThrottled) { return; }
    isThrottled = true;
    setTimeout(function () { isThrottled = false; }, throttleDuration);

    // do your work here
}
