Performance test helper

A tiny module to help test the performance of functions.

It uses perf_hooks (included in Node's standard lib) under the hood.

Usage

const { performanceTestHelper } = require("perf-test-helper");

function functionToTest(numbers) {
  return numbers.reduce((acc, val) => acc + val, 0);
}

const averageTime = performanceTestHelper({
  iterations: 100,
  functionUnderTest: functionToTest,
  parameters: [[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]],
});
// 0.115 (result is in milliseconds)
