How to use `if` logical judgment tags to implement conditional output in Json-LD?

As an experienced website operation expert, I know that in the increasingly fierce online competition, how to make the website content stand out, be accurately understood by search engines, and effectively displayed is the most important part of our work.Structural data (Json-LD) is undoubtedly a powerful tool for improving website visibility and user experience.However, the content of the website changes constantly, and if Json-LD always remains 'unchanged', it cannot fully utilize its advantages.

AnQiCMS, known for its flexibility and ease of use as a content management system, is well-versed in this field. It provides a powerful template engine, allowing us to implement conditional output in Json-LD through logical judgment tags, making your structured data act like an intelligent assistant, 'tailor-made' according to different content.
