TypeError: Invalid attempt to destructure non-iterable instance. On React Native

Question

由于这一行，我收到一个错误 const [guesses, setGuesses] = React.useState < IGuess > defaultGuess; 在 Vscode 上显示 Operator '>' cannot be applied to types 'boolean' and 'IGuess'.ts(2365)

****
interface IGuess {
  [key: number]: string;
}

const defaultGuess: IGuess = {
  0: '',
  1: '',
  2: '',
  3: '',
  4: '',
  5: '',
};

export default function App() {
  const [guesses, setGuesses] = React.useState < IGuess > defaultGuess;
*****

Answer 1

你需要改成这个
const [guesses, setGuesses] = React.useState (defaultGuess)
