Which statement about using setContent is correct?

• A. The callback's content should be used as the source of truth.
• B. The first parameter's content should always be used as the source of truth.
• C. There is no processing of content when setting content.
• D. The content passed into the callback must exactly match the first parameter.

Answer: (A)

When you use setContent, you provide a function that processes content and returns the final version. The value that the callback returns becomes the canonical content you store or render. In other words, the content produced inside the callback, after any processing, is treated as the source of truth, not just the original input you started with. The first parameter is simply the starting point that the callback can read and use, but it isn’t automatically the definitive content. There is processing happening within the callback, and the returned content may differ from the input based on validation, transformation, or dynamic substitutions. So the content you pass into the callback isn’t required to match the first parameter exactly; the callback’s output is what ultimately defines the final content.
