|

|
|
* For when you need a one-liner to collect iterable values.
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
*
|
||
|
|
* ```javascript
|
||
|
|
* import all from 'it-all'
|
||
|
|
*
|
||
|
|
* // This can also be an iterator, etc
|
||
|
|
* const values = function * () {
|
||
|
|
* yield * [0, 1, 2, 3, 4]
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* const arr = all(values)
|
||
|
|
*
|
||
|
|
* console.info(arr) // 0, 1, 2, 3, 4
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Async sources must be awaited:
|
||
|
|
*
|
||
|
|
* ```javascript
|
||
|
|
* const values = async function * () {
|
||
|
|
* yield * [0, 1, 2, 3, 4]
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* const arr = await all(values())
|
||
|
|
*
|
||
|
|
* console.info(arr) // 0, 1, 2, 3, 4
|
||
|
|
* ```
