Reactjs – react hook setEmail giving error with no error message

I have

const [setEmail, email] = useState();

though when I call setEmail("[email protected]") it does not setEmail and it does not give an error message

code

alert("before email - yes)

setEmail([email protected])

alert("after email - no)

alert("after email - no) never gets called? what the actual , no error message given either. and its not to do with @.com as when i call setEmail("sdsafs") it doesn’t work either.

    I think the way you are using the useState hook is wrong. What does useState return? It returns a pair of values: the current state and a function that updates it. This is why we write const [count, setCount] = useState().The order is important here. You have named them the other way. try below,

    const [email, setEmail] = useState();

    also refer https://legacy.reactjs.org/docs/hooks-state.html for how to use useState hook

    You should use useState hook properly. And it is not correct in the use of alert.

    alert("before email - yes");
const [email, setEmail] = useState("");
alert("after email - no");
