+/**
+ * Deeply clones the given object.
+ *
+ * You can customize the deep cloning process using the `cloneValue` function.
+ * The function takes the current value `value`, the property name `key`, and the entire object `obj` as arguments.
+ * If the function returns a value, that value is used;
+ * if it returns `undefined`, the default cloning method is used.
+ *
+ * @template T - The type of the object.
+ * @param obj - The object to clone.
+ * @param [cloneValue] - A function to customize the cloning process.
+ * @returns A deep clone of the given object.
+ *
+ * @example
+ * // Clone a primitive value
+ * const num = 29;
+ * const clonedNum = cloneDeepWith(num);
+ * console.log(clonedNum); // 29
+ * console.log(clonedNum === num); // true
+ *
+ * @example
+ * // Clone an object with a customizer
+ * const obj = { a: 1, b: 2 };
+ * const clonedObj = cloneDeepWith(obj, (value) => {
+ *   if (typeof value === 'number') {
+ *     return value * 2; // Double the number
+ *   }
+ * });
+ * console.log(clonedObj); // { a: 2, b: 4 }
+ * console.log(clonedObj === obj); // false
+ *
+ * @example
+ * // Clone an array with a customizer
+ * const arr = [1, 2, 3];
+ * const clonedArr = cloneDeepWith(arr, (value) => {
+ *   return value + 1; // Increment each value
+ * });
+ * console.log(clonedArr); // [2, 3, 4]
+ * console.log(clonedArr === arr); // false
