How to fix All destructured elements are unused in TypeScript

// WRONG - destructured but not using them
const half = ({ max, min }) => {
  return (stats.max + stats.min) / 2.0; // Using stats instead of max/min
};

// CORRECT - use the destructured variables
const half = ({ max, min }) => {
  return (max + min) / 2.0;
};

// WRONG
const { name, age } = user;
console.log(user.name, user.age); // Not using destructured variables

// CORRECT
const { name, age } = user;
console.log(name, age); // Using destructured variables

// WRONG - unnecessary destructuring
const { id, name } = user;
await saveUser(user);

// CORRECT - just use the object directly
await saveUser(user);

// WRONG
const [first, second] = items;
console.log(items);

// CORRECT
console.log(items);

// Skip first element but keep second
const [_unused, needed] = array;
console.log(needed);

// Extract some properties, ignore others
const { _id, name, email } = user;
console.log(name, email); // Not using _id

{
  "rules": {
    "@typescript-eslint/no-unused-vars": [
      "error",
      {
        "varsIgnorePattern": "^_",
        "destructuredArrayIgnorePattern": "^_"
      }
    ]
  }
}

// Skip first element entirely (no variable created)
const [, second, third] = items;
console.log(second, third);

// Skip middle elements
const [first, , , fourth] = items;
console.log(first, fourth);

// Extract date, keep everything else
const { date, ...rest } = payload;
processData(rest); // Only using rest, not date

{
  "rules": {
    "@typescript-eslint/no-unused-vars": [
      "error",
      {
        "ignoreRestSiblings": true
      }
    ]
  }
}
