* Calls an input function `n` times, returning an array containing the results
|
|
* of those function calls.
|
|
*
|
|
* `fn` is passed one argument: The current value of `n`, which begins at `0`
|
|
* and is gradually incremented to `n - 1`.

|
* @sig (Number -> a) -> Number -> [a]
|
|
* @param {Function} fn The function to invoke. Passed one argument, the current value of `n`.
|
|
* @param {Number} n A value between `0` and `n - 1`. Increments after each function call.
|

* @return {Array} An array containing the return values of all calls to `fn`.
