What is a 'namespace' in a Yeoman generator?

• A. The identifier used to invoke the generator (often derived from the package name after 'generator-'), e.g., 'yo angular' for generator-angular
• B. The package's directory name
• C. The generator's version
• D. The author name

Answer: (A)

The namespace is the command you type after the Yeoman launcher to run a generator. It’s the identifier Yeoman registers for that generator, usually derived from the package name after removing the prefix "generator-". For example, a package named generator-angular becomes the namespace angular, so you invoke it with yo angular. This namespace lets Yeoman know which generator to execute and lets you have multiple generators installed and selectable by their own names. It isn’t the package directory name, nor the generator’s version, nor the author’s name.
