Templating languages are specialized programming languages or systems designed to generate text output based on templates and data. They are commonly used in web development, documentation, and other scenarios where dynamic content generation is required. These languages allow developers to separate the presentation logic from the data, making it easier to manage and update content.

One of the most well-known templating languages is HTML, which is used to structure web pages. However, HTML alone is not sufficient for dynamic content generation. To address this, templating engines like Jinja2 for Python, Twig for PHP, and Handlebars for JavaScript have been developed. These engines allow developers to embed placeholders and control structures within HTML templates, which are then populated with data at runtime.

Templating languages can also be used in documentation generation. Tools like Sphinx for Python and Doxygen for C++ use templating to generate documentation from source code comments. This approach ensures that documentation remains up-to-date with the codebase and reduces the manual effort required to maintain documentation.

In summary, templating languages play a crucial role in modern software development by enabling the separation of content and logic, facilitating dynamic content generation, and improving the maintainability of code and documentation. Their use spans across various domains, including web development, documentation, and more, making them an essential tool for developers.
