+/**
+ * Makes a comparator function out of a function that reports whether the first
+ * element is less than the second.
+ *
+ * @func
+ * @memberOf R
+ * @since v0.1.0
+ * @category Function
+ * @sig ((a, b) -> Boolean) -> ((a, b) -> Number)
+ * @param {Function} pred A predicate function of arity two which will return `true` if the first argument
+ * is less than the second, `false` otherwise
+ * @return {Function} A Function :: a -> b -> Int that returns `-1` if a < b, `1` if b < a, otherwise `0`
+ * @example
+ *
+ *      const byAge = R.comparator((a, b) => a.age < b.age);
+ *      const people = [
+ *        { name: 'Emma', age: 70 },
+ *        { name: 'Peter', age: 78 },
+ *        { name: 'Mikhail', age: 62 },
+ *      ];
+ *      const peopleByIncreasingAge = R.sort(byAge, people);
+ *        //=> [{ name: 'Mikhail', age: 62 },{ name: 'Emma', age: 70 }, { name: 'Peter', age: 78 }]
