Array reducing utility.
```bash
npm install arrayreduce --save
```
+ [Concat Array](#concat-array)
+ [Boolean And](#boolean-and)
+ [Boolean Or](#boolean-or)
+ [Index By Attr](#index-by-attr)
### Concat Array
`arraysort.arrayConcat()` create a function which reduce entries as concatenated array.
```javascript
"use strict";
const arrayreduce = require('arrayreduce');
// Define a reducing function.
let arrayConcat = arrayreduce.arrayConcat();
// Execute sorting.
let values = ['foo', ['bar', 'baz']].reduce(arrayConcat, []);
console.log(values); // -> ['foo', 'baz', 'bar']
```
### Boolean And
`arraysort.booleanAnd()` create a function which reduce entries with and condition.
```javascript
"use strict";
const arrayreduce = require('arrayreduce');
// Define a reducing function.
let booleanAnd = arrayreduce.booleanAnd();
// Execute reducing.
let result = [true, false, true].reduce(booleanAnd, true);
console.log(result); // -> false
```
### Boolean Or
`arraysort.booleanOr()` create a function which reduce entries with and condition.
```javascript
"use strict";
const arrayreduce = require('arrayreduce');
// Define a reducing function.
let booleanOr = arrayreduce.booleanOr();
// Execute reducing.
let result = [true, false, true].reduce(booleanOr, true);
console.log(result); // -> true
```
### Index By Attr
`arraysort.indexByAttr()` create a function which reduce entries to index object.
```javascript
"use strict";
const arrayreduce = require('arrayreduce');
// Define a reducing function.
let indexByAttr = arrayreduce.indexByAttr();
// Execute indexing.
let index = [
{id: 1, name: 'foo'},
{id: 2, name: 'bar'}
].reduce(indexByAttr('id'), {});
console.log(index); // -> {'1': {id: 1, name: 'foo'}, '2': {id: 2, name: 'bar'}}
