Code Blocks

def fibonacci(n):
    """Generate Fibonacci sequence up to n terms."""
    if n <= 0:
        return []
    elif n == 1:
        return [0]
    elif n == 2:
        return [0, 1]
    
    sequence = [0, 1]
    for i in range(2, n):
        sequence.append(sequence[i-1] + sequence[i-2])
    
    return sequence

# Example usage
print(fibonacci(10))

// JavaScript example
const fetchUserData = async (userId) => {
  try {
    const response = await fetch(`/api/users/${userId}`);
