Counts the number of items in an async iterable

About

Counts the number of items in an (async)iterable.

N.b. will consume the iterable

Example

import length from 'it-length'

// This can also be an iterator, generator, etc
const values = [0, 1, 2, 3, 4]

const res = length(values)

console.info(res) // 5

Async sources must be awaited:

import length from 'it-length'

const values = async function * () {
  yield * [0, 1, 2, 3, 4]
}

const res = await length(values())

console.info(res) // 5

Install

$ npm i it-length

Browser <script> tag
