# Streams for `fp-ts` 

This library provides `Stream` and `AsyncStream` type classes which uses

`Generator` and `AsyncGenerator` internally, therefore enabling the developers

to have _transducers_, that are executed as much as they are used. See the

following example:

```ts

import { range, filter, map, take, toArray } from 'fp-ts-stream/Stream'

import { pipe } from 'fp-ts/lib/function'

// The following will only run/execute the `range` iterator only 4 times.

//

// No array will be allocated, until `toArray` and the rest of the iteration

// will be skipped/not completed.

pipe(

  range(0, 10000),            // iterates 4 times

  filter(it => it % 2 == 1),  // iterates 2 times

  map(it => it * 3),          // ...

  take(2),                    // ...

  toArray,                    // executed once

  console.log

)

```

The `Stream` is implementing all the functions that an array would normally

have, therefore the instances of it admit implementations such as `Traversable`,

`Chain` and etc.
