+/**
+ * Creates a function that removes leading values while a predicate returns true.
+ *
+ * Once the predicate returns false, that value and all following values are
+ * emitted. The returned function is lazy-capable inside {@link pipe}.
+ *
+ * @template T - The type of elements in the array.
+ * @param predicate - Called with each leading value and index while values are being dropped.
+ * @returns A function that maps the piped array to the remaining suffix.
+ *
+ * @example
+ * import { dropWhile, pipe } from 'es-toolkit/fp';
+ *
+ * pipe([1, 2, 3, 1], dropWhile(value => value < 3));
+ * // => [3, 1]
