In Yeoman, when you compose with another generator using this.composeWith, what is the primary effect?

• A. It duplicates the main generator's logic
• B. It prevents any templates from being generated
• C. It adds functionality from the other generator to the main one
• D. It runs the other generator only after the main one finishes

Answer: (C)

The key idea is that composing with another generator brings in that generator’s capabilities into your main generator. When you call this.composeWith, Yeoman runs the other generator as part of the same run, allowing its prompts, actions, and file-generation steps to be integrated with yours. This lets you reuse and extend functionality without duplicating code, effectively adding the other generator’s features to the main one. It’s not about duplicating your own logic, nor about preventing templates, and it isn’t strictly limited to running after the main generator finishes—the composed generator runs within the same run flow and contributes its outputs as part of the process.
