Score Analysis

Score 0: 'Weak'
Score 1: 'Weak'
Score 2: 'Fair'
Score 3: 'Good'
Score 4: 'Strong'

Based on your requirement disable the submit button according to the score.

Let say if your preferred score is 3 then you can disable the submit button if the score is less than 3.

export default function App() {
  const [password, setPassword] = React.useState({ value: '', error: '' });
  const [passwordScore, setPasswordScore] = React.useState(0);
  const _updateScore = (val: any) => {
    setPasswordScore(val);
