What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:

For almost a year now, I've been using this "flux" architecture to organize my React applications and to work on other people's projects, and its popularity has grown quite a lot, to the point where it shows up on job listings for React and a lot of people get confused about what it is.

Why I'm tired of using and teaching flux

There are a billion explainations on the internet, so I'll skip explaining the parts. Instead, let's cut to the chase -- the main parts I hate about flux are the Dispatcher and the Store's own updating mechanism.

If you use a setup similar to the examples in facebook/flux, and you use flux.Dispatcher, you probably have this kind of flow:

app.directive('faFastScroll', ['$parse', function ($parse) {
  var Interval = function(min, max) {
    this.min = min || 0;
    this.max = max || 0;
  };

  Interval.prototype.clip = function(min, max) {
    if(this.max <= min || this.min >= max) {
      this.min = this.max = 0;

(function() {
  // Do not use this library. This is just a fun example to prove a
  // point.
  
  var Bloop = window.Bloop = {};

  var mountId = 0;
  function newMountId() {
    return mountId++;
  }
