I am try to my best register on firebase authentication but I am facing some problems.

I am try to like this code but it's not working.

const hadleToLogin = async event => {
    event.preventDefault();
    let email = event.target.email.value
    const password = event.target.password.value
    console.log(email, password)
    await signInWithEmailAndPassword(email, password);



    if (user) {
        navigate('/home');
    }

}

const navigateRegister = () => {
    navigate('/register')
}
const resetPassword = async () => {
    const email = emailRef.current.value;
    if (email) {
        await sendPasswordResetEmail(email);
        toast('sent email');
    }
    else{
        toast('enter a valid email')
    }
}
