| Test case name | Result |
|---|---|
| lodash | |
| Native |
| Test name | Executions per second |
|---|---|
| lodash | 16647.4 Ops/sec |
| Native | 264109.4 Ops/sec |
The test results indicate that the _.values(obj) function (which is part of Lodash) performs significantly better than the native Object.values(obj) function in terms of speed.
From the benchmark result, we can see that:
Object.values(obj) function executed 16647.435546875 times per second on a Chrome 95 browser on a Windows device._.values(obj) function executed 264109.375 times per second on the same browser and device.This suggests that Lodash's implementation of values is significantly faster than the native JavaScript method. This is likely due to various optimization techniques used in Lodash's implementation, such as memoization or caching, which can reduce the overhead of function calls and improve performance.
