This Babel plugin transforms Unicode property regexes (e.g., /\p{Emoji}/u) into equivalent, but more widely supported, ES5 code. It expands these modern regex features to ensure broader browser compatibility, enabling developers to use expressive Unicode patterns without sacrificing support for older JavaScript environments. The plugin leverages regular expression transformations to achieve this, improving runtime performance across diverse browsers. By incorporating this, projects can adopt contemporary regex syntax while maintaining a consistent user experience.
