What programming model does Liferay primarily use for front-end development?

Liferay primarily utilizes JSP (JavaServer Pages) and Alloy UI for front-end development, which is why this choice is considered correct. JSP allows for dynamic content generation on the server side, which integrates seamlessly with Java-based back-end processes. This makes it a core component of Liferay's architecture, enabling the generation of HTML content efficiently.

Alloy UI, on the other hand, is a JavaScript framework that facilitates the development of interactive user interfaces within Liferay applications. It enhances the user experience by providing a rich set of UI components and patterns specifically designed to work in conjunction with Liferay's environment.

While JavaScript and Bootstrap, or HTML, CSS, and JavaScript are relevant technologies in modern web development, they do not encapsulate the primary programming model used by Liferay. Many developers use these technologies alongside Liferay, but they do not form the core development framework that Liferay emphasizes. Similarly, while frameworks like Angular and React are popular for building modern applications, they do not represent the foundational technologies Liferay is built on or primarily promotes for front-end development.
