Benchmark: filter vs slice - MeasureThat.net

Script Preparation code:

var small = Array.from({ length: 10 }, (_, i) => i);
var medium = Array.from({ length: 100 }, (_, i) => i);
var large = Array.from({ length: 1000 }, (_, i) => i);
var xlarge = Array.from({ length: 10000 }, (_, i) => i);
var xxlarge = Array.from({ length: 100000 }, (_, i) => i);
var xxxlarge = Array.from({ length: 1000000 }, (_, i) => i);
var xxxxlarge = Array.from({ length: 10000000 }, (_, i) => i);

var filter = (arr, index) => arr.filter((_, i) => i !== index);

var slice = (arr, index) => [...arr.slice(0 ,index), ...arr.slice(index+1)];

It seems like you're providing a JSON-formatted string of data that appears to be related to browser performance testing results.

If I were to parse this data, here are some observations and findings:

**Browser Patterns**

The majority of the `RawUAString` values follow a similar pattern: "Mozilla/5.0 (Windows NT [version]; Win64; x64) AppleWebKit/[version] (KHTML, like Gecko) Chrome/[version].0.0.0 Safari/[version].36 Edg/[version].0.0.0". The variations in `[version]` and the presence of different `Safari` versions suggest that the data spans a range of browser releases.

**OS and Device Platform**

The `OperatingSystem` and `DevicePlatform` fields are consistently set to "Windows" across all test cases, indicating that these tests were likely run on Windows desktops.

**Test Cases**

There are six distinct test case names: "slice medium", "slice large", "filter large", "slice xlarge", "filter xlarge", "slice xxlarge", and "filter xxlarge". These names suggest a focus on varying the size of data slices (or filters) being tested, possibly to evaluate performance under different conditions.

**Performance Metrics**

The `ExecutionsPerSecond` values provide insight into the relative performance of each test case. For example, the first two test cases ("slice medium" and "slice large") have significantly higher execution rates than the later test cases with larger data slices (e.g., "slice xlarge", "filter xlarge").

**Other Observations**

* Some test cases have very high execution rates (>100 executions per second), while others are much slower (<10 executions per second).
* The majority of tests were performed with Chrome 129, but some had Safari and Edge versions as well.
* There's a notable decrease in performance as the data slice size increases.

Please let me know if you'd like me to extract any specific insights or provide further analysis on these findings!
