I'd be happy to help explain the benchmark and its results.

**What is being tested?**

The provided benchmark tests two different approaches to concatenate strings in JavaScript:

1. **Simple string concatenation**: The first test case, `"+"` , tests the performance of simply concatenating two strings using the `+` operator.
2. **Function call with string concatenation**: The second test case, `"Func +"`, tests the performance of calling a function that returns a string and then concatenating it with another string.

**Options being compared**

The benchmark compares two approaches:

1. **Simple string concatenation**: This approach uses the `+` operator to concatenate strings.
2. **Function call with string concatenation**: This approach calls a function that returns a string, which is then concatenated with another string using the same `+` operator.

**Pros and cons of each approach**

1. **Simple string concatenation**
	* Pros: Simple, straightforward, and widely supported.
	* Cons: Can lead to performance issues if used excessively due to the creation of temporary objects and strings.
2. **Function call with string concatenation**
	* Pros: Encapsulates the string concatenation logic, making it easier to reuse and maintain. Can also provide a way to add additional processing steps before concatenation.
	* Cons: May incur performance overhead due to function calls and potentially unnecessary object creation.

**Library usage**

There is no library explicitly mentioned in the provided benchmark definition or test cases. However, some libraries might be used indirectly through the JavaScript runtime environment (e.g., Chrome's V8 engine).

**Special JS feature/syntax**

The benchmark does not seem to use any special JavaScript features or syntax beyond standard ECMAScript.

**Alternatives**

Other alternatives for string concatenation in JavaScript include:

1. **String.prototype.concat()**: This method is available on the String prototype and can be used to concatenate strings.
2. **Array.prototype.join()**: This method is available on Array prototypes and can be used to concatenate arrays into a single string.
3. **Template literals**: Introduced in ECMAScript 2015, template literals provide a concise way to concatenate strings using the `${}` syntax.

Keep in mind that these alternatives might not be as widely supported or efficient as the simple `+` operator approach.
