The code comment redundancy epidemic has reached street signs! Just like that sign helpfully pointing out "THIS IS A STOP SIGN" under an actual stop sign, junior devs have a special talent for writing comments that state the painfully obvious:
// This function adds two numbers
function add(a, b) {
return a + b; // Returns the sum
}
Senior devs scrolling through that code base are experiencing physical pain right now. Remember folks: good comments explain why, not what. Unless you're documenting an API, in which case... carry on with your obvious statements!
