# example
```
var reduce = require('array-reduce');
var xs = [ 1, 2, 3, 4 ];
var sum = reduce(xs, function (acc, x) { return acc + x }, 0);
console.log(sum);
```
output:
```
10
```
# methods
``` js
var reduce = require('array-reduce')
```
## var res = reduce(xs, f, init)
Create a result `res` by folding `acc = f(acc, xs[i], i)` over each element in
the array `xs` at element `i`. If `init` is given, the first `acc` value is
`init`, otherwise `xs[0]` is used.
