how to clear state in react hooks
const { useState } = React;
function signupUser() {
return new Promise(resolve => {
setTimeout(resolve, 1000);
});
}
const initialState = {
username: "",
email: "",
password: "",
passwordConfirmation: ""
};
const Signup = () => {
const [
{ username, email, password, passwordConfirmation },
setState
] = useState(initialState);
const clearState = () => {
setState({ ...initialState });
};
const onChange = e => {
const { name, value } = e.target;
setState(prevState => ({ ...prevState, [name]: value }));
};
const handleSubmit = e => {
e.preventDefault();
signupUser().then(clearState);
};
return (
<form onSubmit={handleSubmit}>
<div>
<label>
Username:
<input value={username} name="username" onChange={onChange} />
</label>
</div>
