logical-assignment-operators

📝 Require or disallow logical assignment operator shorthand.

💼🚫 This rule is enabled in the ✅ recommended config. This rule is disabled in the ☑️ unopinionated config.

🔧💡 This rule is automatically fixable by the --fix CLI option and manually fixable by editor suggestions.

This rule is the same as the built-in ESLint logical-assignment-operators rule, but when enforceForIfStatements is enabled, falsy if assignments are reported with suggestions for both ||= and ??= instead of being autofixed.

Consistently choosing logical-assignment shorthand or an explicit assignment or conditional makes updates easier to scan and avoids mixing the same pattern in different forms.

Replacement for ESLint logical-assignment-operators

This rule replaces ESLint's built-in logical-assignment-operators rule, which Unicorn presets disable when this rule is enabled.
