LLMs can make mistakes. Check important info.

I'll summarize the benchmark results for you:

**Benchmark Comparison**

The benchmark results compare the execution time of different functions that manipulate JSON objects in JavaScript.

**Comparison Winners:**

* **Original Gangster**: 100,6660 executions per second
* **Uglified (minified)**: 100,1145.875 executions per second

**Other Results:**

* **Loop Not Map (still recursive)**: 747257.125 executions per second
* **Hand rolled**: 14,802.44921875 executions per second
* **Json Clone**: 13,385.056640625 executions per second
* **Lodash cloneDeep**: 12,757.12890625 executions per second
* **Ramda clone**: 7,106.529296875 executions per second

**Observations:**

* The original gangster function remains the fastest.
* The minified (uglified) version of the function is slightly slower than the original but still respectable.
* Other optimized functions, such as those using Lodash or Ramda, are significantly slower than the original and minified versions.

Please note that these results might not be accurate or representative due to potential issues with benchmarking tools or variations in test environments.
