What specific section or headline is this issue about?

Concatenation in context

What information was incorrect, unhelpful, or incomplete?

The demo code uses prompt() to demonstrate concatenation. However, when the button is clicked, the prompt call from the code snippet context is ignored, and the displayed message immediately becomes "Hello null, nice to see you!“

Chromium browsers log: "Ignored call to 'prompt()'. The document is sandboxed, and the 'allow-modals' keyword is not set."

What did you expect to see?

A pop-up prompt asking "What is your name?"
