## Description

Super-expressive is a zero-dependency JavaScript library and domain-specific language used to construct complex regular expressions. It functions as a pattern generator that uses natural language syntax to produce native regular expression objects or strings, supporting international text standards through Unicode property matching.

The library replaces manual string manipulation and escaping with a method-chaining fluent interface. It allows for modular expression composition, enabling the creation of reusable pattern hierarchies where existing expression instances can be nested as subexpressions.

The tool covers a broad range of matching primitives, including anchor constraints, capture groups, quantifiers, and lookaround assertions. It also provides utilities for character class and set definitions, as well as the configuration of global matching flags like case-insensitivity and multiline mode.
