As we were preparing Playwright 1.1.0, I learned quite a lot about Web Proxies. Below is the summary of my findings.

TIL: WEB Proxies

Reverse Web Proxy vs Forwarding Web Proxy

There are two groups of proxies that drive internet:

new Intl.NumberFormat(undefined, {
    notation: 'compact'
}).format(12200);
// "12K"

new Intl.NumberFormat(undefined, {
    notation: 'compact'
}).format(12534200);
// "13M"

	// str_replace removes the JS part and makes it into a normal JSON file	
	$followers=json_decode(str_replace('window.YTD.follower.part0 = ','',file_get_contents(__DIR__.'/followers.js')),true);

	echo "\n\n";
	echo number_format(count($followers)).' followers';
	echo "\n\n";

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

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
