I am reading the following tutorial.

What is the problem with the following code:

function withdraw(uint amount) public {
     require(balances[msg.sender] >= amount);
     balances[msg.sender] -=amount;
     payable(msg.sender).transfer(amount);
     transactions++;
}

How is this code causing reentrancy attack?

There is nothing in the page about reentrancy attacks. What makes you think that code is vulnerable? – Lauri Peltonen Jan 20 '21 at 17:09
