What role do "JavaScript modules" play in Liferay?

JavaScript modules play a significant role in Liferay by encapsulating reusable functionality and enabling modular development. This approach allows developers to organize code into distinct, manageable pieces that can be imported or exported as needed. By using modules, developers can avoid code duplication, simplify maintenance, and enhance collaboration within teams. Each module can focus on a specific task or set of functionalities, promoting clean and efficient code structure.

The modularity provided by JavaScript modules aligns well with modern development practices, such as using frameworks like React or Angular, which Liferay supports through its frontend development features. This allows for a more structured and scalable approach to building user interfaces and ensures that functionalities can be reused across different parts of the application without redundancy.
