# eslint-plugin/prefer-object-rule

📝 Disallow function-style rules.

💼 This rule is enabled in the ✅ `recommended` [config](https://github.com/eslint-community/eslint-plugin-eslint-plugin#presets).

🔧 This rule is automatically fixable by the [`--fix` CLI option](https://eslint.org/docs/latest/user-guide/command-line-interface#--fix).

Prior to ESLint v9, ESLint supported both [function-style](https://eslint.org/docs/latest/extend/custom-rules-deprecated) and [object-style](https://eslint.org/docs/latest/extend/custom-rules) rules. However, function-style rules have been deprecated since 2016, and do not support newer features like autofixing and suggestions.

As of [ESLint v9](https://github.com/eslint/rfcs/tree/main/designs/2021-schema-object-rules#motivation-for-requiring-object-style-rules), ESLint supports only object-style rules.
