LLMs can make mistakes. Check important info.

The benchmark data appears to be related to comparing two objects, `foo4` and `bar4`, using both the native JavaScript `===` operator (equals) and the Lodash library's `isEqual` function.

Here is a summary of the benchmark results:

1. The native JavaScript `===` operator:
	* For the test case "equals 4", the average executions per second are 8783.611328125.
	* For the test case "isEqual", the average executions per second are 7692.42578125.
2. The Lodash library's `isEqual` function:
	* Both tests have similar execution rates, with an average of around 7700-8800 executions per second.

Based on these results, it appears that the native JavaScript `===` operator is slightly faster than the Lodash library's `isEqual` function for this specific test case. However, the difference is relatively small and may not be significant in most cases.

It's also worth noting that the Chrome browser version used in the benchmark (86) might influence the results, as different versions of the browser can have varying performance characteristics.
