Accepted Answer

### 💡 How to Think About This Problem
When implementing **Compose functions list** 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 **Compose functions list**:
* **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: Right to Left Reduce** - Apply functions from right to left using `reduceRight`.
  * **Step 2: Async compatibility** - Intercept values; if a Promise is detected, chain downstream functions via `then()`.
  * **Step 3: Boundary returns** - Return identity functions when argument parameters are empty.
