Native Array Performance Testing

This is the simplest example for testing JavaScript's native Array.prototype.map performance.

nativeJsArrayPerformance.js
content_copyfile_download
const timerName = 'Array Map'

const initialArray = (
  Array(10000000)
  .fill(null)
)

console
.time(timerName)

initialArray
.map(String)

console
.timeEnd(timerName)
