/**
 * Returns a new list containing the last `n` elements of a given list, passing
 * each value to the supplied predicate function, and terminating when the
 * predicate function returns `false`. Excludes the element that caused the
 * predicate function to fail. The predicate function is passed one argument:
 * *(value)*.
 *
 * @func
 * @memberOf R
 * @since v0.16.0
 * @category List
 * @sig (a -> Boolean) -> [a] -> [a]
 * @sig (a -> Boolean) -> String -> String
 * @param {Function} fn The function called per iteration.
 * @param {Array} xs The collection to iterate over.
 * @return {Array} A new array.
 * @see R.dropLastWhile, R.addIndex
 * @example
 *
 *      const isNotOne = x => x !== 1;
 *
 *      R.takeLastWhile(isNotOne, [1, 2, 3, 4]); //=> [2, 3, 4]
 *
 *      R.takeLastWhile(x => x !== 'R' , 'Ramda'); //=> 'amda'
