Object map transformations

Question

Accepted Answer

### 💡 How to Think About This Problem
When implementing **Object map transformations** in a frontend interview, candidate developers should focus on structural correctness, managing execution bindings, and minimizing performance overhead.

#### 1. Deconstructing the Requirements
To build a robust solution for **Object map transformations**:
* **Inputs/Outputs**: Validate parameter types, handling boundary values such as empty values, null properties, or negative constraints cleanly.
* **Design Philosophy**: Break the problem down into small, composable operations that are easy to test.

#### 2. Step-by-Step Walkthrough

* **Step-by-Step Walkthrough**:
  * **Step 1: Deep Recursive mapping** - Recursively map nested children structure, handling both Arrays and Objects.
  * **Step 2: Cycle check Map** - Log visited maps to bypass reference cycles.
  * **Step 3: Symbol keys support** - Capture both standard string keys and Symbol keys.

#### 3. Complexity & Memory Analysis
* **Time Comple
