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

method 1

sudo /usr/local/McAfee/AntiMalware/VSControl stopoas

alternatively

sudo defaults write /Library/Preferences/com.mcafee.ssm.antimalware.plist OAS_Enable -bool False
sudo /usr/local/McAfee/AntiMalware/VSControl stop
sudo /usr/local/McAfee/AntiMalware/VSControl reload

The introduction to Reactive Programming you've been missing

Are your feelings hurt?

If you rushed through David Shariff's JS Quiz or are just new to JS they might be. I know mine were. After I dried my eyes, I took the quiz again, this time very slowly trying to get at the meat behind each answer. Below is my attempt to explain each question's answer and offer some interesting permutations so that others can move beyond their hurt feelings and come out the other side better JS developers.

I initially thought I'd turn this into a blog post but think it's probably better as a gist.

Question #1

Don't over think it.

var foo = function foo() {

	#!/bin/bash
	killall aria2c &>/dev/null
	list=`wget -qO- https://raw.githubusercontent.com/ngosang/trackerslist/master/trackers_all.txt\|awk NF\|sed ":a;N;s/\n/,/g;ta"`
	if [ -z "`grep "bt-tracker" /aria/aria2.conf`" ]; then
	sed -i '$a bt-tracker='${list} /aria/aria2.conf
	echo add......starting
	sleep 3
	sudo -u www-data aria2c --conf-path=/aria/aria2.conf -D
	ps -aux\|grep aria
	else

	const compose = (...fns) => (...args) => {
	return fns.slice(0, -1).reduceRight((res, fn) => fn(res),
	fns[fns.length -1].apply(null,args)
	);
	};

	const pipe = (f1, ...fns) => (...args) => {
	return fns.reduce((res, fn) => fn(res), f1.apply(null,args));
	};
