What tool is used for rapidly creating new projects using generators in Liferay?

The tool used for rapidly creating new projects using generators in Liferay is Yeoman. Yeoman serves as a scaffolding tool that simplifies the creation and management of web applications by providing templates and generators specific to various frameworks and environments. In the context of Liferay, Yeoman can help developers quickly set up a project structure and include necessary dependencies and configurations, allowing them to focus on building their applications without starting from scratch.

Other tools mentioned, such as Gulp, NPM, and Node.js, serve different purposes in the development ecosystem. Gulp is primarily a task runner used for automating tasks like minification and compilation. NPM (Node Package Manager) helps in managing packages and dependencies but does not create project structures by itself. Node.js is a runtime for executing JavaScript on the server-side but does not provide project scaffolding features. Thus, Yeoman stands out as the dedicated tool for project generation in Liferay.
