// JavaScript example with async/await
async function fetchUserData(userId) {
  try {
    const response = await fetch(`/api/users/${userId}`);
    const userData = await response.json();
    return userData;
  } catch (error) {
    console.error('Failed to fetch user data:', error);
    throw error;
  }

Python example with class definition:
# Python class with type hints
from typing import List, Optional
class TaskManager:
    def __init__(self) -> None:
        self.tasks: List[str] = []
    def add_task(self, task: str) -> None:
        """Add a new task to the list."""
        self.tasks.append(task)
    def get_task(self, index: int) -> Optional[str]:
        """Get a task by index, return None if not found."""
        return self.tasks[index] if 0 <= index < len(self.tasks) else None
