methods

=======

``` js

```

concatMap(xs, fn)

-----------------

Return an array of concatenated elements by calling `fn(x, i)` for each element

`x` and each index `i` in the array `xs`.

When `fn(x, i)` returns an array, its result will be concatenated with the

result array. If `fn(x, i)` returns anything else, that value will be pushed

onto the end of the result array.
