# stream-reduce

Like [`Array.prototype.reduce`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce)

but for streams. Given a sync reduce function and an initial value it

will return a through stream that emits a single data event with the

reduced value once the input stream ends.

# Example

```js

var reduce = require("stream-reduce");

process.stdin.pipe(reduce(function(acc, data) {

	return acc + data.length;

}, 0)).on("data", function(length) {

	console.log("stdin size:", length);

});

```

# Installation

```

npm install stream-reduce

```
