How AI Agents can help to improve productivity of Developer

// AI Agent identifies potential issues:

// ❌ Potential Issue: Missing error handling
const fetchUserData = async (userId) => {
  const response = await fetch(`/api/users/${userId}`);
  return response.json(); // What if response is not ok?
};

// ✅ AI Suggested Fix:
const fetchUserData = async (userId) => {
  try {
    const response = await fetch(`/api/users/${userId}`);
    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }
    return await response.json();
  } catch (error) {
    console.error('Failed to fetch user data:', error);
    throw error;
  }
};

/**
 * AI-generated comprehensive documentation
 * 
 * Calculates the compound interest for a given principal amount
 * @param {number} principal - The initial amount of money
 * @param {number} rate - The annual interest rate (as a decimal)
 * @param {number} time - The time period in years
 * @param {number} compound - The number of times interest is compounded per year
 * @returns {number} The final amount after compound interest
 * 
 * @example
 * // Calculate compound interest for $1000 at 5% for 2 years, compounded quarterly
 * const result = calculateCompoundInterest(1000, 0.05, 2, 4);
 * console.log(result); // 1104.49
 * 
 * @throws {Error} Throws an error if any parameter is negative

// Error: Cannot read property 'name' of undefined

// AI Analysis:
// The error occurs because 'user' object is undefined when trying to access 'name' property
// This typically happens when:
// 1. API call hasn't completed yet
// 2. User data failed to load
// 3. Component rendered before data was available

// AI Suggested Solutions:

// Solution 1: Add null check
const UserComponent = ({ user }) => {
  if (!user) {
    return <div>Loading...</div>;
  }
  return <div>{user.name}</div>;
};

// Solution 2: Use optional chaining
const UserComponent = ({ user }) => {
  return <div>{user?.name || 'Unknown User'}</div>;
};

// Solution 3: Provide default props
UserComponent.defaultProps = {
  user: { name: 'Guest' }
};
