AI Code Review Examples

A basic JavaScript file analyzed for performance optimization and code readability.

// Before
function fetchData() {
  let data = getData();
  for (let i = 0; i < data.length; i++) {
    console.log(data[i]);
  }
}

// After AI Review
function fetchData() {
  const data = getData();
  data.forEach(item => console.log(item));
}

A Python function refactored for better performance and clean coding standards.

# Before
def process_data(data):
    result = []
    for d in data:
        result.append(d * 2)
    return result

# After AI Review
def process_data(data):
    return [d * 2 for d in data]

A C++ program optimized for better memory usage and code simplicity.

// Before
std::vector<int> getSquares(std::vector<int> &nums) {
    std::vector<int> squares;
    for (int i = 0; i < nums.size(); i++) {
        squares.push_back(nums[i] * nums[i]);
    }
    return squares;
}

// After AI Review
std::vector<int> getSquares(const std::vector<int> &nums) {
    std::vector<int> squares(nums.size());
    std::transform(nums.begin(), nums.end(), squares.begin(), [](int n) { return n * n; });
    return squares;
}

A review focused on semantic HTML and CSS best practices for cleaner and more accessible code.

<!-- Before -->
<div class="button" style="color: white; background-color: blue;">Click Me</div>

<!-- After AI Review -->
