/**
 * Returns a new list excluding the leading elements of a given list which
 * satisfy the supplied predicate function. It passes each value to the supplied
 * predicate function, skipping elements while the predicate function returns
 * `true`. The predicate function is applied to one argument: *(value)*.
 *
 * Dispatches to the `dropWhile` method of the second argument, if present.
 *
 * Acts as a transducer if a transformer is given in list position.
 *
 * @func
 * @memberOf R
 * @since v0.9.0
 * @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.takeWhile, R.transduce, R.addIndex
 * @example
 *
 *      const lteTwo = x => x <= 2;
 *
 *      R.dropWhile(lteTwo, [1, 2, 3, 4, 3, 2, 1]); //=> [3, 4, 3, 2, 1]
 *
 *      R.dropWhile(x => x !== 'd' , 'Ramda'); //=> 'da'
