Let's dive into the world of JavaScript microbenchmarks.

**What is tested?**

MeasureThat.net provides a JSON file that represents a benchmark, which in this case is the calculation of the SHA-256 hash of a given string. The benchmark tests four different approaches:

1. **Native**: Uses the Web API `crypto.subtle.digest()` to calculate the SHA-256 hash.
2. **SJCL**: Utilizes the SJCL (Simple JavaScript Cryptography Library) library, specifically the `sjcl.hash.sha256` function, to calculate the SHA-256 hash.
3. **CryptoJS**: Employs the CryptoJS library, which has a `SHA256` function, to calculate the SHA-256 hash.
4. **Forge**: Uses the Forge library, which provides a `SHA256` function, to calculate the SHA-256 hash.

**Options compared**

Each approach uses a different implementation to calculate the SHA-256 hash:

* Native: Uses the Web API's `crypto.subtle.digest()` function, which is a built-in implementation of the SHA-256 algorithm.
* SJCL: Implements the SHA-256 algorithm using native code, providing a more optimized and secure solution.
* CryptoJS: Provides a pre-built SHA-256 function that can be used to calculate hashes.
* Forge: Offers a `SHA256` function that uses a combination of built-in implementations and native code for optimal performance.

**Pros and Cons**

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

* Native:
	+ Pros: Built-in implementation, optimized for performance, secure.
	+ Cons: Limited control over implementation details, may not be available on all browsers.
* SJCL:
	+ Pros: Optimized for performance, secure, provides more control over implementation details.
	+ Cons: Requires additional dependencies (SJCL library), may have slightly slower performance compared to native implementation.
* CryptoJS:
	+ Pros: Easy to use, provides a simple API, can be used in older browsers that don't support Web APIs.
	+ Cons: Not optimized for performance, may not be as secure as native or SJCL implementations.
* Forge:
	+ Pros: Optimized for performance, secure, provides more control over implementation details.
	+ Cons: Requires additional dependencies (Forge library), may have slightly slower performance compared to native implementation.

**Libraries and their purpose**

Here are the libraries used in this benchmark:

* **SJCL**: A simple JavaScript cryptography library that provides a wide range of cryptographic functions, including hash functions like SHA-256. It's designed for ease of use and high performance.
* **CryptoJS**: A popular JavaScript library for cryptographic operations, providing an easy-to-use API for various algorithms, including SHA-256. However, it may not be as optimized or secure as native implementations.
* **Forge**: A C++ library that provides a wide range of cryptographic functions, including hash functions like SHA-256. It's designed for high performance and security, but requires additional dependencies (the JavaScript wrapper).

**Special JS feature/syntax**

This benchmark does not use any special JavaScript features or syntax that are specific to modern browsers.

**Alternatives**

If you're interested in exploring alternative approaches, here are a few options:

* **Web Cryptography API**: This is a newer API that provides more comprehensive support for cryptographic operations, including hash functions.
* **Browser-specific implementations**: Some browsers (e.g., Chrome) provide their own implementation of the SHA-256 algorithm, which can be used instead of the Web API or a library like SJCL or Forge.
