// Which of the 3 of these options is more readable / is easier to understand?

// OPTION 1: .forEach with .push
const subqueries = []
Object.entries(SPECIAL_SUBQUERY_FIELDS).forEach(([field, subquery]) => {
  if (fieldRequested(field, info))
    subqueries.push(`(${subquery} LIMIT 1) AS ${field}`)
})

// OPTION 2: .map with .filter
const subqueries = Object.entries(SPECIAL_SUBQUERY_FIELDS)
  .map(
    ([field, subquery]) =>
      fieldRequested(field, info) && `(${subquery} LIMIT 1) AS ${field}`
  )
  .filter(Boolean)

// OPTION 3: .flatMap
const subqueries = Object.entries(SPECIAL_SUBQUERY_FIELDS).flatMap(
  ([field, subquery]) =>
    fieldRequested(field, info) ? [`(${subquery} LIMIT 1) AS ${field}`] : []
