Script Preparation code:

    cm: new commonmark.HtmlRenderer(),
    mdit: markdownit({
        html: true
    }),

Tests:

Marked
conv.marked(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 {conv.markdown.parse(md());} catch {return null};

Let's break down the benchmark and explain what's being tested, compared options, pros and cons of each approach, and other considerations.

**Benchmark Overview**

The benchmark measures the performance of different JavaScript Markdown implementations: Marked, CommonMark, Markdown-it, Remarkable, Micromarkdown, Snarkdown, and markdown-wasm. The test creates a sample Markdown text and passes it through each implementation to render HTML.

**Test Cases**

Each test case compares the execution speed of one Markdown implementation against another. For example:

* `conv.marked(md());` tests Marked
* `conv.cm.render(pars.cm.parse(md()));` tests CommonMark
* `conv.mdit.render(md());` tests Markdown-it
* And so on

**Implementation Libraries and Purposes**

Here's a brief overview of the libraries used in each implementation:

* **marked**: A lightweight Markdown parser. It's fast but doesn't render HTML.
* **commonmark**: A full-featured Markdown parser that also renders HTML.
* **markdown-it**: A lightweight Markdown parser with HTML rendering capabilities. It's similar to marked but more feature-rich.
* **remarkable**: A Markdown renderer that produces clean, semantic HTML.
* **micromarkdown**: A small and fast Markdown parser.
* **snarkdown**: A simple Markdown parser that also renders HTML.
* **markdown-wasm**: A web-based implementation of markdown-wasm, a WebAssembly-based Markdown parser.

**Comparison Options**

The benchmark compares the following options:

1. **Parse-only vs Render-only**: Some implementations (like marked and micromarkdown) only parse Markdown text without rendering HTML, while others (like commonmark and markdown-it) render HTML from the parsed text.
2. **Lightweight vs Full-featured**: Some implementations (like marked and markdown-wasm) are lightweight and simple, while others (like remarkable and commonmark) are more feature-rich.
3. **WebAssembly-based vs JavaScript-based**: markdown-wasm is a WebAssembly-based implementation, while others are JavaScript-based.

**Pros and Cons**

Here's a brief summary of the pros and cons of each implementation:

* **marked**:
	+ Pros: Lightweight, fast parsing
	+ Cons: Only parses Markdown text, no HTML rendering
* **commonmark**:
	+ Pros: Full-featured, renders HTML, flexible
	+ Cons: Slower than lightweight implementations
* **markdown-it**:
	+ Pros: Fast, feature-rich, renders HTML
	+ Cons: More complex than marked or micromarkdown
* **remarkable**:
	+ Pros: Produces clean, semantic HTML, fast rendering
	+ Cons: More resource-intensive than others
* **micromarkdown**:
	+ Pros: Lightweight, fast parsing, simple
	+ Cons: Limited features compared to other implementations
* **snarkdown**:
	+ Pros: Simple, lightweight, renders HTML
	+ Cons: Fewer features and slower performance than micromarkdown
* **markdown-wasm**:
	+ Pros: WebAssembly-based, fast, lightweight
	+ Cons: Requires modern web browsers to support WASM

**Other Considerations**

The benchmark also shows the execution speed of each implementation on a desktop machine with Chrome 120. This provides insight into how well each implementation performs in real-world usage.

In conclusion, this benchmark helps compare the performance and features of various JavaScript Markdown implementations, providing insights for developers looking to choose an optimal solution for their use case.
