Best practice for using literal strings in GROQ queries with JavaScript client

Not directly a GROQ question but is it better to do
Or

with javascript client?

Better to do the second so it's converted to a string. I believe #1 might not work as it has no quotes around it.

Oh this what a typo from me.The question was more about literal strings with JS and if it's the same in term of performance or something else.

Stitching together queries using template literals is totally fine! But for dynamic values in the query themselves I'd always use $variables and pass them into the query.
