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

	// Lack of tail call optimization in JS
	var sum = function(x, y) {
	return y > 0 ? sum(x + 1, y - 1) :
	y < 0 ? sum(x - 1, y + 1) :
	x
	}

	sum(20, 100000) // => RangeError: Maximum call stack size exceeded

	// Using workaround

	window.$ = document.querySelectorAll.bind(document);

	this.addEventListener(name, fn);
