socket.on('recieve_message', (data) => { console.log('line 80 all comments', allComments) setAllComments((prevAllComments) => { console.log('inside set function', prevAllComments) return [...prevAllComments, data] }) })

Previous to this code block it was just setAllComents. With the addition of an arrow function, the function no longer grabs the original use state but grabs the updated state and appends the data to the array of comments.
