Helpers to measure function execution time. Required for Bestest benchmarking tool.

Example

const { measureFunctionExecution } = require('@bestest/execution')

const testCase = () => Math.random()
const testOptions = {
  maxExecutionsPerSample: Infinity,
  includeDetails: false
}

measureFunctionExecution(testCase, testOptions, measurement => {
  console.log(measurement)

  // Remember, that presented time is in picoseconds (10^-12 s)
  //
  // {
