| var xs = [ 1, 2, 3, 4, 5, 6 ]; |
| var ys = concatMap(xs, function (x) { |
| return x % 2 ? [ x - 0.1, x, x + 0.1 ] : []; |

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