Nunjucks

Nunjucks syntax and patterns are heavily influenced by Jinja2, a Python templating engine, which can be confusing for developers unfamiliar with this style.

While the core functionality is well-documented, advanced features and edge cases often lack detailed guidance or examples, leading to a reliance on community forums which can be sparse.

Nunjucks can suffer from performance degradation when rendering large or deeply nested templates due to its synchronous nature and lack of optimization for such scenarios.

Integrating Nunjucks into a Node.js application for server-side rendering requires additional configuration, including setting up loaders and environments, which can be cumbersome.
