## Array readers and writers

`import { arrayReader, arrayWriter } from 'f-streams'`

-   `reader = arrayReader(array, options)`  
    creates a reader that reads its entries from `array`.  
    `reader.read()` will return its entries asynchronously by default.  
    You can force synchronous delivery by setting `options.sync` to `true`.
-   `writer = arrayWriter(options)`  
    creates a writer that collects its entries into an array.  
    `writer.write(value)` will write asynchronously by default.  
    You can force synchronous write by setting `options.sync` to `true`.
    `writer.toArray()` returns the internal array into which the
    entries have been collected.
