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

Notes from @wesbos's talk:

Our frontend workflow is changing quickly and for good reasons. Tooling for tooling sake is a waste, but don't overlook the utility of modern dev tooling workflows - these are great, useful tools that are letting us improve our workflows in standards-based, forward-looking ways.

Trend: Frontend developers are moving to using package managers (npm) for client-side code (CSS and JS), much like we have been for managing our build tooling itself. I can attest to this being hugely helpful at Filament Group on client-side code, especially now that so many of our projects are on npm (https://www.npmjs.com/~filamentgroup ).

Yay, another talk that recommends loadCSS for performance. Nice to hear :)

function logClass(target: any) {
 
  // save a reference to the original constructor
  var original = target;
 
  // a utility function to generate instances of a class
  function construct(constructor, args) {
    var c : any = function () {
      return constructor.apply(this, args);
