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.
