A HAR archive of the network timings from a compatible browser is extremely useful in pinpointing which issues with Kibana talking to Elasticsearch.

Note on information gathered in a HAR archive

Please note that HAR archives contain sensitive information:

content of the pages you downloaded while recording
your cookies, which will allow anyone with the HAR file to impersonate your account
all the information that you submitted to your browser while recording (i.e., search values, authentication details).

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

#Translating Marty to Redux

Some people have asked how I've translated a Marty app to Redux. Once you get your head around how Redux works I found concepts in Marty translated easily. Below is side-by-side comparison of the two libraries to help you along the way.

Also if you're looking for some devtools, check out redux-devtools.

	// Lazy (=on-demand) zip()
	for (const [i, x] of zip(naturalNumbers(), naturalNumbers())) {
	console.log(i, x);
	if (i >= 2) break;
	}
	// Output:
	// 0 0
	// 1 1
	// 2 2

	This replaces <Sequencer> + multiple <Sampler>s with a marble diagram sequencer.
	You can use it like this:

	<Marble

	samples={[
	'samples/kick.wav',
	'samples/snare.wav',
	]}

	const flattenTco = ([first, ...rest], accumulator) =>
	(first === undefined)
	? accumulator
	: (Array.isArray(first))
	? flattenTco([...first, ...rest])
	: flattenTco(rest, accumulator.concat(first))

	const flatten = (n) => flattenTco(n, []);

	console.log(flatten([[1,[2,[[3]]]],4,[5,[[[6]]]]]))
