The @babel/plugin-transform-property-literals Babel plugin transforms dot notation property access to bracket notation when the property is a reserved word or contains special characters. This optimization ensures compatibility with older JavaScript engines that might not correctly parse such dot notation. For example, foo.default becomes foo['default']. The plugin enhances code robustness across various JavaScript environments, especially when dealing with code that targets older or less standard-compliant interpreters.
