Here, I try to performance benchmark the speed complexity of the native ES6 `Array.map()` over the famous lodash library's `_.map(Array)` function. The results were quite surprising to say the least.

# `[].map()` vs `_.map()`
Here, I try to performance benchmark the speed complexity of the native ES6 `Array.map()` over the famous lodash library's `_.map(Array)` function. The results were quite surprising to say the least.
## Running the Test
```console
$ node test
```
## Reading the Output
Mapping over an Array of **1,000 objects**:
```
ES6 Lodash
Time Elapsed 0.037 ms 0.040 ms
```
Mapping over an Array of **10,000 objects**:
```
ES6 Lodash
Time Elapsed 0.159 ms 0.159 ms
```
Mapping over an Array of **100,000 objects**:
```
ES6 Lodash
Time Elapsed 11.870 ms 1.701 ms
```
Mapping over an Array of **1,000,000 objects**:
```
ES6 Lodash
Time Elapsed 120.790 ms 16.513 ms
```
## Conclusion
We don't tend to see much of a difference with really small arrays (< 10,000 objects), but when it really gets large, which is a rare case on the frontend, lodash seems to be performing better than ES6's own native `.map` function.
If you feel like I have performed the test incorrectly, or you have any other metrics which can be shared, then please fork this repo, make your suggested changes and make a pull request.
