> multithreaded utility functions for node using worker threads

Please ★ this repo if you found it useful ★ ★ ★


## Features

* supports typescript
* customize max threads


## 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

```sh
npm install --save fastdash
```


## Dependencies

* [NodeJS](https://nodejs.org)


## Usage

Iteratee callback functions must be pure functions

### map

```js
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();
```
