| Test case name | Result |
|---|---|
| Delete by Splice | |
| Delete by copyWithin | |
| Delete by Filter |

| Delete by copyWithin | 1.3 Ops/sec |
| Delete by Filter | 1.6 Ops/sec |
Based on the provided benchmark results, I will make an educated guess about which JavaScript method is the fastest.
The benchmark results show:
deleteBySplice with 48.11 executions per second (fps)deleteByFilter with 1.60 fpsdeleteByCopyWithin with 1.29 fpsIt appears that deleteBySplice is the fastest method, followed by deleteByFilter, and then deleteByCopyWithin.
This makes sense because:
deleteBySplice only requires a single operation to delete an element from the array, making it a simple and efficient method.deleteByFilter involves creating a new array with filtered elements, which can be slower due to the extra memory allocation and iteration required.deleteByCopyWithin also involves creating a new array by copying elements from one index to another, which can be slower than using splice or other methods that directly modify the original array.Keep in mind that this is just an educated guess based on the provided benchmark results. The actual performance of each method may vary depending on the specific use case and implementation details.
