 * Flattens a nested object into a single level object with dot-separated keys.

 * @example
 * ```typescript
 * const nestedObject = {
 *   a: {
 *     b: {
 *       c: 1
 *     }
 *   },
 *   d: [2, 3]
 * };
 *
 * const flattened = flattenObject(nestedObject);
 * console.log(flattened);
 * // Output:
 * // {
 * //   'a.b.c': 1,
 * //   'd.0': 2,
 * //   'd.1': 3
 * // }
 * ```

 * @param object - The object to flatten.
