# no-negated-condition

📝 Disallow negated conditions.

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

🔧 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` -->

Negated conditions are more difficult to understand. Code can be made more readable by inverting the condition.

This is an improved version of the [`no-negated-condition`](https://eslint.org/docs/latest/rules/no-negated-condition) ESLint rule that makes it automatically fixable. [ESLint did not want to make it fixable.](https://github.com/eslint/eslint/issues/14792)

## Replacement for ESLint `no-negated-condition`

This rule replaces ESLint's built-in `no-negated-condition` rule, which Unicorn presets disable when this rule is enabled.
