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

**Benchmark Definition**

The benchmark tests how fast two different approaches are to check if an element ('b') exists in an array ['a', 'b', 'c'].

**Test Cases**

There are two test cases:

1. **Vanilla**: This test case uses a built-in JavaScript method, `indexOf()`, to search for the element 'b' in the array.
2. **ramdajs contains**: This test case uses a function from the Ramda library (`R.contains()`) to check if the element 'b' is present in the array.

**Benchmark Results**

The results show how many executions per second (EPS) each approach can handle on a specific device (Chrome 66 on Mac OS X 10.12.6).

**Comparison of Approaches**

Here are the pros and cons of each approach:

### Vanilla (`indexOf()`)

* **Pros**: Built-in method, widely supported by browsers.
* **Cons**: Might be slower due to its general-purpose nature.

### ramdajs (`R.contains()`)

* **Pros**: Might be faster since it's optimized for this specific use case. Also uses a more functional programming style.
* **Cons**: Requires the Ramda library to be loaded, which adds overhead and might not be suitable for all projects.

**Ramda Library**

The Ramda library is a popular JavaScript library that provides functional programming utilities, including data manipulation and transformation functions. In this benchmark, `R.contains()` is used to check if an element exists in an array.

**Other Alternatives**

If you don't want to use the Ramda library, there are other alternatives to achieve similar results:

1. **filter()**: You can use the `filter()` method to create a new array with only the elements that match the condition.
2. **every() and includes()**: In modern browsers, you can use the `every()` method in combination with `includes()` to check if an element exists in an array.

For example:
```javascript
const arr = ['a', 'b', 'c'];
if (arr.every(x => x === 'b')) {
  // do something
}
```
These alternatives might have different performance characteristics and use cases, but they can help you achieve similar results to the original benchmark.
