Regex+ is a JavaScript library that enhances the native RegExp class by adding modern features like atomic groups, subroutines, and context-aware interpolation. It simplifies regex writing with always-on best practices, such as Unicode support and whitespace formatting, making regexes more readable and maintainable. The library is lightweight, supports all ES2026 regex features, and is ideal for developers who want powerful, efficient, and easy-to-read regular expressions without the complexity of legacy syntax.
