GROQ: Using string comparison shorthand within array::join function

Yes, absolutely! Your current approach with the ternary operator (language=="en" ? null : language) works perfectly fine within array::join(), but you can also achieve the same result using the select() function if you prefer that style.

Your current code is totally valid and quite readable:

*[_id in [$published, $draft]] {
  "slug": "/" + array::join(
    array::compact([
      language=="en" ? null : language,
      parent->parent->slug.current,
      parent->slug.current,
      slug.current
    ]), "/"
  )
}

If you wanted to use select() instead, it would look like this:

*[_id in [$published, $draft]] {
  "slug": "/" + array::join(
    array::compact([
      select(language == "en" => null, language),
      parent->parent->slug.current,
      parent->slug.current,
      slug.current
    ]), "/"
  )
}

Both approaches work identically. The select() function evaluates conditions in order and returns the value of the first condition that evaluates to true, or the fallback value (in this case, language) if no conditions match.

Which should you use? It's mostly a matter of preference:

• Ternary operator (condition ? value : fallback) is more concise for simple true/false checks
• select() function shines when you have multiple conditions to check, as it reads more like a switch statement

For your specific use case with a single condition, the ternary operator you're already using is perfectly fine and arguably more readable. The combination with array::compact() elegantly removes the null values for English language slugs, giving you clean URL paths.
