maxperf

Javascript max perf FTW

This package is a collection of small utilities that can replace native code for max perf

Map

Replace Array.proptype.map I mostly use this in JSX mapping

Usage

const map = require("maxperf/map")
 
assert.deepEqual(
  map([1, 2, 3, 4, 5], val => val * val),
  [1, 2, 3, 4, 5].map(val => val * val)
)
