I'll break down the benchmark definition, options compared, pros and cons, library usage, special JavaScript features, and alternatives for this specific test case.

**Benchmark Definition**

The test case is defined using two different methods to compare two arrays: `_.isEqual(window.foo1, window.bar1)` and `JSON.stringify(window.foo1) === JSON.stringify(window.bar1)`.

**Options Compared**

1. **_.isEqual**: A function from the Lodash library that compares two values for equality.
2. **JSON.stringify**: A built-in JavaScript function that converts a value to a string representation.

**Pros and Cons of Each Approach**

1. **_.isEqual**:
	* Pros: Fast, efficient, and accurate for complex data structures like arrays with nested objects.
	* Cons: Requires Lodash library, which may not be included in all environments.
2. **JSON.stringify**:
	* Pros: Built-in, no external dependencies required, and fast for simple data structures.
	* Cons: May not work correctly for complex data structures, especially those with non-serializable values (e.g., functions, undefined).

**Library Usage**

The Lodash library is used in the first test case (`_.isEqual(window.foo1, window.bar1)`). Lodash provides a set of functional programming helpers, including `isEqual`, which can be useful for comparing complex data structures.

**Special JavaScript Features**

None mentioned in this benchmark definition. However, it's worth noting that the use of `window` and `global` variables may not be suitable for all environments or use cases.

**Alternatives**

1. **Array.prototype.every**: Instead of using Lodash's `isEqual`, you could use Array.prototype.every() to check if every element in one array matches the corresponding element in another array.
2. **JSON.stringify + Object.keys()**: For a more complex comparison, you could use JSON.stringify() and then compare the resulting strings with Object.keys(). However, this approach may still be slower than using Lodash's `isEqual`.
3. **Simple loop-based comparison**: You could write a simple loop to iterate through both arrays and check if each element is equal. This approach would have the lowest overhead but might be more prone to errors.

Here's an example implementation of one of these alternatives:
```javascript
// Alternative 1: Using Array.prototype.every()
_.isEqual = (arr1, arr2) => {
  return arr1.every((element, index) => {
    return JSON.stringify(arr1[index]) === JSON.stringify(arr2[index]);
  });
}
```
Keep in mind that the choice of approach depends on the specific requirements and constraints of your project.
