Let's break down what's being tested in this JavaScript microbenchmark.

**Benchmark Overview**

The benchmark is comparing the performance of two approaches: using Ramda.js, a functional programming library, and vanilla JavaScript (the native, built-in JavaScript API).

**Options Being Compared**

1. **Ramda.js (`ramdajs contains`)**: This approach uses Ramda.js to perform the `contains` operation on an array.
2. **Vanilla JavaScript (`arr.includes('a')`)**: This approach uses native JavaScript's `includes` method to check if a value exists in an array.

**Pros and Cons of Each Approach**

1. **Ramda.js (`ramdajs contains`)**:
	* Pros:
		+ Provides a consistent, predictable way to perform functional programming operations.
		+ Can be more efficient for certain data structures or operations.
	* Cons:
		+ Adds extra overhead due to the library itself and its implementation.
		+ May not optimize as well for specific use cases or browsers.
2. **Vanilla JavaScript (`arr.includes('a')`)**:
	* Pros:
		+ Native support, so no additional overhead from a library.
		+ Optimized for most use cases and browsers.
	* Cons:
		+ Can be slower or less predictable than Ramda.js for certain operations.
		+ May not provide the same level of functional programming abstractions.

**Library: Ramda.js**

Ramda.js is a popular functional programming library for JavaScript. It provides a set of functions that can be used to perform common data transformations and operations, such as filtering, mapping, reducing, and checking for membership (like `contains`).

In this benchmark, Ramda.js is used to provide a consistent way to perform the `contains` operation on an array. This allows users to compare its performance with native JavaScript's `includes` method.

**Special JS Feature/Syntax: None**

There are no special JavaScript features or syntax used in this benchmark that require explanation.

**Other Alternatives**

For those interested in alternative approaches, some other options could be:

1. **Lodash**: Another popular utility library for JavaScript, which provides a similar set of functional programming functions as Ramda.js.
2. **ES6+ Array Methods**: Using modern JavaScript array methods like `some()`, `findIndex()`, or `includes()` can also be used to perform membership checks.

Keep in mind that the choice of library or approach ultimately depends on the specific use case, performance requirements, and personal preference.

I hope this explanation helps!
