It seems like you're describing a large dataset of JavaScript benchmark results, possibly from a performance comparison or benchmarking platform.
To answer your question without the actual data, I'll provide some general insights:
splice() method to delete elements from an array. The results show that Chrome 123 performs well on this operation.copyWithin() method is used to create a shallow copy of a portion of an array and then delete elements from the original array. The results indicate that Chrome 123 also performs well on this operation.filter() method to delete elements from an array based on a condition. The results show that Chrome 123 has a slower performance compared to the other two operations.Keep in mind that these are general observations and may not reflect your specific use case or environment. The actual performance of JavaScript operations can be influenced by various factors, such as the size of the input array, the complexity of the operation, and the hardware capabilities of the system running the benchmark.
If you'd like to discuss this topic further or have any more questions, feel free to ask!
