Module it-peekable

Example

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 ]
Copy

Async sources must be awaited:

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 ]
Copy
