/**
* 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'
