+/**
+* Removes elements from the end of an array until the predicate returns false.
+*
+* This function iterates over an array from the end and drops elements 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 from the end,
+* 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 = dropRightWhile(array, x => x > 3);
+* // result will be [1, 2, 3] since elements greater than 3 are dropped from the end.
