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.
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:
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)
)
$ npm i it-foreach
