The community member is confused about when to use the ${} syntax in JavaScript. The comments explain that ${} is an interpolation syntax used to insert variables into strings. The community members discuss that this is a standard JavaScript syntax, and if in doubt, they can ask an AI assistant like this one for clarification.
I don't really need help. Just something that's unclear to me. Sometimes we need to put a var inside ${...} and sometimes we don't? I am sure this makes total sense to anyone who knows why. But I think it's an example of the type of thing that can be confusing for 'no-coders'.
