/*
This snippet is an example of backpressure implementation in Go.
It doesn't run in Go Playground, because it starts an HTTP Server.

The example starts an HTTP server and sends multiple requests to it. The server starts denying
requests by replying an "X" (i.e. a 502) when its buffered channel reaches capacity.

This is not the same as rate-limiting; you might be interested in https://github.com/juju/ratelimit
or https://godoc.org/golang.org/x/time/rate.

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
