Invokes the passed function for each item in an iterable
npm install it-foreach
> Invokes the passed function for each item in an iterable
Calls a function for each value in an (async)iterable.
The function can be sync or async.
Async functions can be awaited on so may slow down processing of the (async)iterable.
``javascript
import each from 'it-foreach'
import drain from 'it-drain'
// This can also be an iterator, generator, etc
const values = [0, 1, 2, 3, 4]
// prints [0, 0], [1, 1], [2, 2], [3, 3], [4, 4]
const arr = drain(
each(values, console.info)
)
`
Async sources and callbacks must be awaited:
`javascript
import each from 'it-foreach'
import drain from 'it-drain'
const values = async function * () {
yield * [0, 1, 2, 3, 4]
}
// prints [0, 0], [1, 1], [2, 2], [3, 3], [4, 4]
const arr = await drain(
each(values(), console.info)
)
`
`console`
$ npm i it-foreach
