Tests:

compress fflate
// The default compression method is gzip // Increasing mem may increase performance at the cost of memory // The mem ranges from 0 to 12, where 4 is the default fflate.compressSync(buf, { level: 6, mem: 8 });
compress lz-string
LZString.compressToUTF16(string);
compress shorty
shorty.deflate(string)
decompress lz-string
LZString.decompressFromUTF16(lzStringCompressed);
decompress shorty
shorty.inflate(shortyCompressed)
decompress fflate
fflate.decompressSync(fflateCompressed);

Let's break down the benchmark and explain what is being tested.

**Benchmark Overview**

The benchmark measures the performance of three compression libraries: `fflate`, `lz-string`, and `shorty`. The test cases include both compression and decompression operations.

**Compression Algorithms**

1. **`fflate`**: A fast and efficient compression library that uses LZ77, a dictionary-based compression algorithm.
2. **`lz-string`**: A JavaScript implementation of the LZ-String compression algorithm, which is similar to Gzip but more optimized for web use cases.
3. **`shorty`**: A lightweight, open-source compression library developed by Evan Hahn. It uses a combination of Huffman coding and LZ77-like algorithms.

**Compression Options**

For `fflate`, the benchmark tests different compression levels (from 0 to 9) with varying amounts of memory allocation (`mem`). This allows testing the trade-off between performance and memory usage.

For `lz-string`, the benchmark tests the compression algorithm without any additional options, as specified in the benchmark definition.

For `shorty`, the benchmark uses the default compression settings provided by the library.

**Pros and Cons**

* **`fflate`**:
	+ Pros: High compression ratios, fast decompression.
	+ Cons: Requires more memory for higher compression levels.
* **`lz-string`**:
	+ Pros: Fast compression, suitable for web use cases.
	+ Cons: May not be as efficient as `fflate` or `shorty`.
* **`shorty`**:
	+ Pros: Lightweight, easy to use, fast compression and decompression.
	+ Cons: May not match the performance of `fflate` or `lz-string`.

**Library Descriptions**

1. **`LZString`**: A JavaScript library for LZ-String compression and decompression. It's optimized for web use cases and provides a simple API for compression and decompression.
2. **`Shorty`**: A lightweight, open-source compression library developed by Evan Hahn. It uses a combination of Huffman coding and LZ77-like algorithms to achieve fast compression and decompression.

**Special Notes**

The benchmark uses Chrome 129 as the browser, which is an older version that may not be supported by all systems. The benchmark also skips any preamble or introductory content, as requested.

By running this benchmark, you can compare the performance of these three compression libraries in terms of compression ratio, decompression speed, and memory usage. This can help you choose the most suitable library for your specific use case.
