Tests:

Marked
conv.marked.parse(md());
CommonMark
conv.cm.render(pars.cm.parse(md()));
Markdown-it
conv.mdit.render(md());
Remarkable
conv.remarkable.render(md());
Micromarkdown
conv.micromarkdown.parse(md(),true);
Snarkdown
conv.snarkdown(md());
markdown-wasm
try {markdown.parse(md());} catch {}
markdown-wasm-alt
try {markdownaltw.parse(md());} catch {}

**Overview**

MeasureThat.net is a website that allows users to create and run JavaScript microbenchmarks, comparing the performance of different Markdown implementations. In this explanation, we'll break down what's being tested on the provided JSON data.

**Benchmark Comparison**

The benchmark compares six Markdown libraries:

1. Marked
2. CommonMark
3. Markdown-it
4. Remarkable
5. Micromarkdown
6. Snarkdown

Each library is compared to its own "wasm" version (markdown-wasm and markdownaltw). The "wasm" versions are likely compiled versions of the libraries for web use.

**Options Compared**

The options being compared are:

* **Parsing**: Each Markdown library is tested with a specific parser:
	+ CommonMark: `new CommonMark.Parser(input)`.
	+ Marked: `marked.parse(input)`.
	+ Markdown-it: `markdownit.markdownit.parser(input)`.
	+ Remarkable: `remark().parse(input)`.
	+ Micromarkdown: `micromark(markdown, input)`.
	+ Snarkdown: `snarkdown(input)`.
* **Rendering**: Each library is tested with a rendered output:
	+ Each library is used to render the same Markdown input, and the execution time is measured.

**Browsers and Platforms**

The benchmark runs on Chrome 117 (version 114.0.0.0) across various platforms:

* Windows
* Desktop

Each browser/platform combination measures the executions per second for each Markdown library.

**What's Being Asked**

To answer this question, we need to know: **"Which Markdown library is fastest?"**
