userData is not defined no-undef

Question

This is my first time using ReactJS and I keep getting error

'userData' is not defined no-undef

even when I declare it. Here's my code:

 class Register extends Component { constructor(props) { super(props); this.state = { userData: [], fullName: "", email: "", uname: "", pass: "" } } onRegis = () => { const { fullName, email, uname, pass } = this.state userData = [{fullName, email, uname, pass}] this.setState({ userData }) console.log("Datanya euy: ", userData) // console.log(email, " is ", fullName, "'s email addres with username ", uname, " and password ", pass); } }`

Answer 1

You forgot define variable userData by var , let or const

const userData = [{fullName, email, uname, pass}];
