# About
An iterable that you can push values into.
## Example
```js
import { pushable } from 'it-pushable'
const source = pushable()
setTimeout(() => source.push('hello'), 100)
setTimeout(() => source.push('world'), 200)
setTimeout(() => source.end(), 300)
const start = Date.now()
for await (const value of source) {
console.log(`got "${value}" after ${Date.now() - start}ms`)
}
console.log(`done after ${Date.now() - start}ms`)
// Output:
// got "hello" after 105ms
// got "world" after 207ms
// done after 309ms
```
## Example
```js
import { pushableV } from 'it-pushable'
import all from 'it-all'
const source = pushableV()
source.push(1)
source.push(2)
source.push(3)
source.end()
console.info(await all(source))
// Output:
// [ [1, 2, 3] ]
```
