7 * Takes a list of predicates and returns a predicate that returns true for a
8 * given list of arguments if every one of the provided predicates is satisfied
9 * by those arguments.
10 *
11 * The function returned is a curried function whose arity matches that of the
12 * highest-arity predicate.
13 *
14 * @func
15 * @memberOf R
16 * @since v0.9.0
17 * @category Logic
18 * @sig [(*... -> Boolean)] -> (*... -> Boolean)
19 * @param {Array} predicates An array of predicates to check
20 * @return {Function} The combined predicate
21 * @see R.anyPass, R.both
22 * @example
23 *
24 * const isQueen = R.propEq('Q', 'rank');
25 * const isSpade = R.propEq('♠︎', 'suit');
26 * const isQueenOfSpades = R.allPass([isQueen, isSpade]);
27 *
28 * isQueenOfSpades({rank: 'Q', suit: '♣︎'}); //=> false
29 * isQueenOfSpades({rank: 'Q', suit: '♠︎'}); //=> true
