    31  ``` js

    33  ```
    34  
    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.
    44
