limited-map

Async map function with limited concurrency for JavaScript. This is a replacement for Promise.all(items.map(asyncCallback)). For example, this is useful if you have an API that you don't want to overload with your request flood.

Example

``javascript
const limitedMap = require("limited-map");

async function fetchDocs() {
const docs = await limitedMap(urls, url => getJSON(url), 30);
return docs;
}
`

API

`javascript
limitedMap(
items: Array,
callback: (item: T, index: number, array: Array) => Promise,
concurrency: number
): Promise>
``
