Possible disadvantages of prism.js

    Prism.js focuses on simple syntax highlighting and doesn't include advanced features like IDE-level code analysis or linting, which some users might expect.
  • Limited Plugin Ecosystem
    While there are several plugins available, the ecosystem isn't as extensive as some other larger projects, which may limit customization for more advanced use cases.

    Some alternative libraries offer built-in advanced line highlighting features, which are not included out of the box in Prism.js, requiring additional customization.
