|
---|
31 | ``` js
|
---|
32 | var concatMap = require('concat-map')

35 | concatMap(xs, fn)
|
---|
36 | -----------------
|
---|
37 |
|
---|
38 | Return an array of concatenated elements by calling `fn(x, i)` for each element
|
---|
39 | `x` and each index `i` in the array `xs`.
|
---|
40 |
|
---|
41 | When `fn(x, i)` returns an array, its result will be concatenated with the
|
---|
42 | result array. If `fn(x, i)` returns anything else, that value will be pushed
|
---|
43 | onto the end of the result array.
