What version of Oxlint are you using?

1.51.0

What command did you run?

npx oxlint

What does your .oxlintrc.json (or oxlint.config.ts) config file look like?

{
  "env": {
    "browser": true,
    "node": true,
    "jest": true
  },
  "categories": {
    "correctness": "error"
  },
  "plugins": ["import", "unicorn", "typescript", "oxc", "vue"],
  "rules": {
    "prefer-const": ["error", { "destructuring": "all" }],
  }
}

What happened?

Ran oxlint on the following with prefer-const set to "prefer-const": ["error", { "destructuring": "all" }],

async function destroyItems() {
  return Promise.resolve(4);
}


async function myFunction() {
  let nItemsDestroyed: number;
  nItemsDestroyed = await destroyItems();
  nItemsDestroyed += await destroyItems();
  console.info(`destroyItem: ${nItemsDestroyed} items destroyed.`);
}

myFunction();

And got the false positive report:

  × eslint(prefer-const): `nItemsDestroyed` is never reassigned.
   ╭─[index.ts:7:7]

   ·       ───────────────
 8 │   nItemsDestroyed = await destroyItems();
   ╰────
  help: Use `const` instead.

ESLint does not flag on the same configuration.
