Script Preparation code:

function simpleStringify(o) {
  let cache = [];

      if (cache.indexOf(value) !== -1) {
        // Circular reference found, discard key
        return;
      }
      // Store value in our collection
      cache.push(value);
    }
    return value;
  });
  cache = null;
  return data;

Measuring performance differences between two approaches for serializing JavaScript objects is an interesting task.

**Benchmark Definition**

The benchmark definition consists of two scripts: `simpleStringify` and `JSON.stringify`. The `simpleStringify` function manually implements the serialization process, while `JSON.stringify` uses the built-in JSON serializer.

**Options Compared**

*   **Simple Stringification (manual implementation)**:
    *   Pros:
        *   Can potentially provide more control over the serialization process.
        *   May be able to optimize for specific use cases.
    *   Cons:
        *   Requires manual implementation, which can increase complexity and debugging time.
        *   May not be optimized for general-purpose serialization.
*   **JSON Stringification (built-in)**:
    *   Pros:
        *   Widely supported and well-tested.
        *   Optimized for performance and compatibility.
    *   Cons:
        *   Less control over the serialization process.
        *   May not be able to optimize for specific use cases.

**Library Used**

The `simpleStringify` function uses a simple caching mechanism to avoid serializing circular references. The cache is implemented using an array (`cache`), which stores values that have already been serialized.

**Individual Test Cases**

There are two test cases:

*   **simpleStringify**: This test case runs the `simpleStringify(testData)` function, where `testData` is a complex JavaScript object containing various serializable and non-serializable properties.
*   **JSON.stringify**: This test case runs the `JSON.stringify(testData)` function, which serializes the same `testData` object using the built-in JSON serializer.

**Latest Benchmark Result**

The latest benchmark result shows that:

*   The `simpleStringify` approach has a higher execution frequency per second (103578.625) compared to the `JSON.stringify` approach (54183.125). However, this may be due to the caching mechanism in `simpleStringify`, which avoids unnecessary serializations.
*   Both approaches have similar performance characteristics on this specific test case.

In conclusion, while the `simpleStringify` function provides more control over the serialization process, it also introduces additional complexity and debugging time. The built-in `JSON.stringify` function is widely supported, optimized for performance, and suitable for most use cases.
