5 * Returns `true` if no elements of the list match the predicate, `false`
6 * otherwise.
7 *
8 * Dispatches to the `all` method of the second argument, if present.
9 *
10 * Acts as a transducer if a transformer is given in list position.
11 *
12 * @func
13 * @memberOf R
14 * @since v0.12.0
15 * @category List
16 * @sig (a -> Boolean) -> [a] -> Boolean
17 * @param {Function} fn The predicate function.
18 * @param {Array} list The array to consider.
19 * @return {Boolean} `true` if the predicate is not satisfied by every element, `false` otherwise.
20 * @see R.all, R.any
21 * @example
22 *
23 * const isEven = n => n % 2 === 0;
24 * const isOdd = n => n % 2 !== 0;
25 *
26 * R.none(isEven, [1, 3, 5, 7, 9, 11]); //=> true
27 * R.none(isOdd, [1, 3, 5, 7, 8, 11]); //=> false
