  • Learning Dependency
    Users may become reliant on pre-built regex patterns and not fully learn regex construction, potentially limiting their deeper understanding.
  • Limited Language Support
    Primarily focuses on JavaScript regex, which may not fully cover the syntax and nuances of regex in other programming languages like Python or PHP.
