Benchmarks

map benchmarks

These benchmarks were performed on a server with 8 cores to show the contrast between multithreaded and single threaded node processing.

A function calculates prime numbers to simulate a workload.

map()	CPU Intensive	CPU Nonintensive
fastdash	2741.328177 ms	322.372878 ms
lodash	10367.716365 ms	0.271168 ms

fastdash is multithreaded and is faster than lodash for CPU intensive tasks.

lodash is single threaded and is slower than fastdash for CPU intensive tasks.

lodash is faster than fastdash for tasks that are not CPU intensive.

Installation

npm install --save fastdash

Dependencies

• NodeJS

Usage

Iteratee callback functions must be pure functions

map

import fast from 'fastdash';

async main() {
  const result = await fast.map([1, 2, 3], item => {
    return item + 1;
  });
  console.log(result); // [2, 3, 4]
}

main();
