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

**Benchmark Overview**

The benchmark is designed to compare the performance of two equality functions: Lodash's `isEqual` function and Ramda's `equals` function (without relying on currying or composition). The test case uses a predefined JSON data structure (`source`) to calculate the equality between identical and slightly modified versions of it (`source2`).

**Tested Options**

The benchmark tests two main options:

1. **Lodash Equality**: Lodash's `isEqual` function is used to compare the `source` and `source2` objects.
2. **Ramda Equality**: Ramda's `equals` function (without relying on currying or composition) is used to compare the `source` and `source2` objects.

**Pros and Cons**

* **Lodash Equality**: Lodash's `isEqual` function is a well-established and widely-used equality function. It has some advantages, such as:
	+ Wide support for various data structures (arrays, objects, etc.)
	+ Built-in handling of primitive types
	+ Easy to use and understand
However, it also has some potential drawbacks:
	+ May be slower than optimized implementations due to its higher-level abstraction
	+ Can lead to unnecessary computations if used with complex or deeply nested objects

* **Ramda Equality**: Ramda's `equals` function is a lightweight and efficient implementation of equality checking. It has some advantages, such as:
	+ Faster execution times compared to Lodash
	+ More tailored for functional programming use cases
	+ Fewer dependencies on external libraries
However, it also has some potential drawbacks:
	+ May be less intuitive or easier to learn for developers without prior experience with Ramda
	+ Less flexible handling of primitive types

**Library and Syntax**

* **Lodash**: Lodash is a popular JavaScript utility library that provides a wide range of functions for various tasks, including equality checking. The `isEqual` function in the benchmark uses the `lodash.isEqual` method.
* **Ramda**: Ramda is a lightweight functional programming library that provides an efficient implementation of equality checking through its `equals` function.

**Special JS Features or Syntax**

The benchmark does not use any special JavaScript features or syntax beyond what's typical for modern JavaScript code. It only uses standard ES6+ syntax and built-in libraries like Lodash and Ramda.

**Alternatives**

Other alternatives for equality checking in JavaScript include:

* **JavaScript's `===` operator**: While it can be used for simple cases, it may not cover all edge cases or work with certain data structures.
* **ES6's `Object.is()` method**: This method is available on modern browsers and provides a more precise comparison for objects.
* **Custom implementations**: Depending on the specific requirements, developers might choose to implement their own equality checking logic from scratch.

Keep in mind that these alternatives may not offer the same level of performance or flexibility as optimized libraries like Lodash and Ramda.
