# Disallow `if` statements as the only statement in `if` blocks without `else`

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

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

<!-- end auto-generated rule header -->
<!-- Do not manually modify this header. Run: `npm run fix:eslint-docs` -->

This rule adds onto the built-in [`no-lonely-if`](https://eslint.org/docs/rules/no-lonely-if) rule, which only disallows `if` statements in `else`, not in `if`. It is recommended to use `unicorn/no-lonely-if` together with the core ESLint `no-lonely-if` rule.
