prefer-identifier-import-export-specifiers

📝 Prefer identifiers over string literals in import and export specifiers.

💼 This rule is enabled in the following configs: ✅ recommended, ☑️ unopinionated.

🔧 This rule is automatically fixable by the --fix CLI option.

Prefer identifier syntax over string-literal syntax in import and export specifiers and import attribute keys when the string is a valid identifier name.

This rule does not require all specifiers to use the same style. Use string literals when the imported or exported name cannot be written as an identifier.
