+/**
+ * A function wrapping calls to the two functions in an `||` operation,
+ * returning the result of the first function if it is truth-y and the result
+ * of the second function otherwise. Note that this is short-circuited,
+ * meaning that the second function will not be invoked if the first returns a
+ * truth-y value.
+ *
+ * In addition to functions, `R.either` also accepts any fantasy-land compatible
+ * applicative functor.

+ * @category Logic
+ * @sig (*... -> Boolean) -> (*... -> Boolean) -> (*... -> Boolean)
+ * @param {Function} f a predicate
+ * @param {Function} g another predicate
+ * @return {Function} a function that applies its arguments to `f` and `g` and `||`s their outputs together.
+ * @see R.both, R.or
+ * @example
+ *
+ *      const gt10 = x => x > 10;
+ *      const even = x => x % 2 === 0;
+ *      const f = R.either(gt10, even);
+ *      f(101); //=> true
+ *      f(8); //=> true
+ *
+ *      R.either(Maybe.Just(false), Maybe.Just(55)); // => Maybe.Just(55)
+ *      R.either([false, false, 'a'], [11]) // => [11, 11, "a"]
