/**
* A function which calls the two provided functions and returns the `&&`
* of the results.
* It returns the result of the first function if it is false-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
* false-y value.
*
* In addition to functions, `R.both` also accepts any fantasy-land compatible
* applicative functor.
*
* @func
* @memberOf R
* @since v0.12.0
* @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.either, R.allPass, R.and
* @example
*
* const gt10 = R.gt(R.__, 10)
* const lt20 = R.lt(R.__, 20)
* const f = R.both(gt10, lt20);
* f(15); //=> true
* f(30); //=> false
*
* R.both(Maybe.Just(false), Maybe.Just(55)); // => Maybe.Just(false)
* R.both([false, false, 'a'], [11]); //=> [false, false, 11]
