How do themelets benefit Liferay themes?

Themelets in Liferay themes serve the specific purpose of enhancing customization while maintaining efficiency. By using themelets, developers can create modular components that can easily be integrated into various themes. This modularity significantly reduces the amount of repetitive or boilerplate code that would otherwise be required when developing custom themes.

The ability to cut down on boilerplate code is a primary advantage of themelets. They allow developers to focus on the unique aspects of a theme rather than rewriting common elements, which streamlines the development process. This results in cleaner, more maintainable code and a faster development cycle, as developers can reuse these components across different themes.

While themelets do promote reusability and efficiency, they are not designed for creating entirely new themes from scratch. Additionally, they are not limited to Java development; their primary function is in the context of front-end theming, which includes CSS, HTML, and JavaScript. Finally, contrary to the notion that they cannot be used across different themes, themelets are explicitly designed for cross-theme use, allowing for more versatile application throughout various projects.
