Counts the number of items in an async iterable
npm install it-length
> Counts the number of items in an async iterable
Counts the number of items in an (async)iterable.
N.b. will consume the iterable
``javascript
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:
`javascript
import length from 'it-length'
const values = async function * () {
yield * [0, 1, 2, 3, 4]
}
const res = await length(values())
console.info(res) // 5
`
`console`
$ npm i it-length
