* @packageDocumentation
|
|
*
|
|
* Lets you look at the contents of an async iterator and decide what to do
|
|
*
|
|
* @example
|
|
*
|
|
* ```javascript
|
|
* import peekable from 'it-peekable'
|
|
*
|
|
* // This can also be an iterator, generator, etc
|
|
* const values = [0, 1, 2, 3, 4]
|
|
*
|
|
* const it = peekable(value)
|
|
*
|
|
* const first = it.peek()
|
|
*
|
|
* console.info(first) // 0
|
|
*
|
|
* it.push(first)
|
|
*
|
|
* console.info([...it])
|
|
* // [ 0, 1, 2, 3, 4 ]
|
|
* ```
|
|
*
|
|
* Async sources must be awaited:
|
|
*
|
|
* ```javascript
|
|
* import peekable from 'it-peekable'
|
|
*
|
|
* const values = async function * () {
|
|
* yield * [0, 1, 2, 3, 4]
|
|
* }
|
|
*
|
|
* const it = peekable(values())
|
|
*
|
|
* const first = await it.peek()
|
|
*
|
|
* console.info(first) // 0
|
|
*
|
|
* it.push(first)
|
|
*
|
|
* console.info(await all(it))
|
|
* // [ 0, 1, 2, 3, 4 ]
|
|
* ```
