# @kessler/async-map-limit

A `Promise.all()` based implementation for doing async map with limit on concurrency.

`impl.js` contains my experiments with various methods to do it.

`bench` compares them using two different benchmark modules

```js

const map = require('@kessler/async-map-limit')

main()

async function main() {

    // process the array, 2 items at a time 

    const result = await map([1, 2, 3, 4, 5, 6], asyncMapper, 2)

}

function asyncMapper(value) {

    return new Promise((resolve) => {

        setImmediate(() => resolve(value))

    })

}

```
