2/**
3 * Calls an input function `n` times, returning an array containing the results
4 * of those function calls.
5 *
6 * `fn` is passed one argument: The current value of `n`, which begins at `0`
7 * and is gradually incremented to `n - 1`.
8 *
9 * @func
10 * @memberOf R
11 * @since v0.2.3
12 * @category List
13 * @sig (Number -> a) -> Number -> [a]
14 * @param {Function} fn The function to invoke. Passed one argument, the current value of `n`.
15 * @param {Number} n A value between `0` and `n - 1`. Increments after each function call.
16 * @return {Array} An array containing the return values of all calls to `fn`.
17 * @see R.repeat
18 * @example
19 *
20 * R.times(R.identity, 5); //=> [0, 1, 2, 3, 4]
21 * @symb R.times(f, 0) = []
22 * @symb R.times(f, 1) = [f(0)]
23 * @symb R.times(f, 2) = [f(0), f(1)]
