+/**
+ * Removes elements from the beginning of an array until the predicate returns false.
+ *
+ * This function iterates over an array and drops elements from the start until the provided
+ * predicate function returns false. It then returns a new array with the remaining elements.
+ *
+ * @template T - The type of elements in the array.
+ * @param arr - The array from which to drop elements.
+ * @param canContinueDropping - A predicate function that determines
+ * whether to continue dropping elements. The function is called with each element, and dropping
+ * continues as long as it returns true.
+ * @returns A new array with the elements remaining after the predicate returns false.
+ *
+ * @example
+ * const array = [1, 2, 3, 4, 5];
+ * const result = dropWhile(array, x => x < 3);
+ * // result will be [3, 4, 5] since elements less than 3 are dropped.
