I'll break down the explanation into smaller parts.

**Benchmark Definition JSON**

The provided Benchmark Definition JSON represents a JavaScript benchmark with two test cases. Here's what each field does:

* `Name`: The name of the benchmark, which in this case is "function name length".
* `Description`: An optional description of the benchmark, but it's left blank for this example.
* `Script Preparation Code` and `Html Preparation Code`: These fields are empty, indicating that no specific setup or preparation code needs to be executed before running the benchmarks.

**Individual Test Cases**

The test cases are defined in two separate objects:

1. The first object defines a benchmark with a long function name:
```javascript
function thisIsAReallyReallyReallyReallyReallyReallyReallyReallyReallyReallyReallyReallyReallyReallyReallyReallyReallyLongFunctionName() {
  return 1;
}
thisIsALongFunctionName();
```
The purpose of this test case is to measure the performance impact of having a very long function name.

2. The second object defines a benchmark with a short function name:
```javascript
function x() {
  return 1;
}
x();
```
This test case measures the performance impact of having a short function name.

**Library and Purpose**

There are no libraries explicitly mentioned in the Benchmark Definition JSON or the individual test cases. However, it's worth noting that some JavaScript engines might have specific optimizations or caching mechanisms for functions with certain characteristics, such as long names.

**Special JS Features/Syntax**

There is one special feature/syntax used in these benchmarks: variable declarations (`let`, `const`, etc.) are not explicitly mentioned, but function declarations and calls are. The use of a long function name might have implications for the performance of JavaScript engines due to potential string pooling or caching mechanisms.

**Other Alternatives**

For measuring JavaScript performance, there are several alternatives to MeasureThat.net:

1. JSPerf: A popular benchmarking tool specifically designed for JavaScript performance testing.
2. Benchmark.js: A lightweight library for benchmarking JavaScript code.
3. WebPageTest: A comprehensive tool for testing web page performance, which includes JavaScript benchmarks.

Keep in mind that each of these tools has its own strengths and weaknesses, and some might be more suitable for specific use cases or performance profiling scenarios.
