Fleti NPM | npm.io

Introduction

This repository had two goals:

Check the speed difference in all major browsers of ]for let i, for ... of, filter/forEach/map/reduce using playwright
Check if it would be faster to use the same system of callbacks from filter/forEach/map/reduce/ but while using a wrapper around for let i

Benchmark

Dataset: [Math.random() * 100; 10_000_000]

Tries: 10

To avoid as much engine optimization as possible a new dataset is created before each function run (aka try).

All values that you'll find below are in milliseconds
