Autogenerated LLM Summary (model llama3.2:3b, generated 27 days ago):

LLMs can make mistakes. Check important info.

It appears that you are providing a benchmarking test case with four different methods to clone or serialize a JavaScript object: `_.cloneDeep`, `structuredClone`, `JSON.parse(JSON.stringify)`, and others.

To answer your question, here is the updated output:

1.  **Lodash Clone Deep**: The latest benchmark result for this method is 0.007 seconds (5463 executions per second).
2.  **Structured Clone**: The latest benchmark result for this method is 0.012 seconds (5375 executions per second).
3.  **JSON.parse(JSON.stringify)**: The latest benchmark result for this method is 0.021 seconds (3620 executions per second).

Note that these results are based on the provided benchmarking data and may vary depending on the specific use case and system configuration.

Additionally, I will provide a summary of the latest benchmark results:

**Benchmark Summary**
