Which helper does Yeoman provide to template files using EJS?

• A. this.fs.copy
• B. this.fs.copyTpl
• C. this.fs.template
• D. this.fs.render

Answer: (B)

When you want to fill in placeholders in template files during generation, you use the helper that processes EJS templates and writes the rendered content to the destination. This is this.fs.copyTpl. It reads a source template, runs it through EJS with a data object you provide, and writes the result to the target file. For example, you pass in your template path, the destination path, and an object like { title: this.props.title, name: this.props.name } so the template can render those values.

Copying simply duplicates files without processing templates, so this.fs.copy would leave the content unchanged. The other methods aren’t part of Yeoman’s file system API for templating, so they don’t perform the EJS rendering you need.
