Let's break down the benchmark and explain what's being tested.
Benchmark Overview
The provided JSON represents a JavaScript microbenchmark that compares two approaches: using Lodash (lodash
) for flatMap functionality versus native implementation (i.e., without any external library).
What is tested?
flatMap
function.flatMap
function.The test cases are designed to measure the performance difference between these two approaches.
Options Compared:
Pros and Cons
The choice between using Lodash (flatMap
) or native implementation depends on your specific needs:

When choosing between these two approaches, keep in mind:
Additional Notes
The benchmark tests are designed to compare the performance difference between these two approaches. The test case uses an array x
with three elements [1, 2, 3]
, and for each element, it generates two new arrays using a lambda function ([x-1, x, x+1]
).
