| /** |
| * Like [`reduce`](#reduce), `reduceWhile` returns a single item by iterating |
| * through the list, successively calling the iterator function. `reduceWhile` |
| * also takes a predicate that is evaluated before each step. If the predicate |
| * returns `false`, it "short-circuits" the iteration and returns the current |
| * value of the accumulator. |
| * |
| * @func |
| * @memberOf R |
| * @since v0.22.0 |
| * @category List |
| * @sig ((a, b) -> Boolean) -> ((a, b) -> a) -> a -> [b] -> a |
| * @param {Function} pred The predicate. It is passed the accumulator and the |
| * current element. |
| * @param {Function} fn The iterator function. Receives two values, the |
| * accumulator and the current element. |
| * @param {*} a The accumulator value. |
| * @param {Array} list The list to iterate over. |
| * @return {*} The final, accumulated value. |
| * @see R.reduce, R.reduced |
| * @example |
| * |
| * const isOdd = (acc, x) => x % 2 === 1; |
| * const xs = [1, 3, 5, 60, 777, 800]; |
| * R.reduceWhile(isOdd, R.add, 0, xs); //=> 9 |
| * |
| * const ys = [2, 4, 6] |
| * R.reduceWhile(isOdd, R.add, 111, ys); //=> 111 |
