const [title,setTitle] = useState("");
const titleHandler=e => {
setTitle(e.target.value)
console.log(title)
}
Why does this code log the old value of title and not the new one. I'm new to js and react please can anyone explain this to me

it happend because when you call setTitle it doesn't update the state instantaneously but it trigger a rerender of the component with the updated state
if you do
const [title,setTitle] = useState("");
const titleHandler=e => {
setTitle(e.target.value)
console.log('updating title')
}
useEffect(() => {
console.log('title updated', title)
}, [title])
you can see for yourself
