Based on a user review, provide a product rating as an integer between 1 and 5. \n
Only output the integer.

Review: "${review}"
Rating:

`Analyze a product review, and then based on your analysis give me the
corresponding rating (integer). The rating should be an integer between 1 and
5. 1 is the worst rating, and 5 is the best rating. A strongly dissatisfied
review that only mentions issues should have a rating of 1 (worst). A strongly
satisfied review that only mentions positives and upsides should have a rating
of 5 (best). Be opinionated. Use the full range of possible ratings (1 to
5). \n\n
    \n\n
    Here are some examples of reviews and their corresponding analyses and
    ratings:
    \n\n
    Review: 'Stylish and functional. Not sure how it'll handle rugged outdoor
    use, but it's perfect for urban exploring.'
    Analysis: The reviewer appreciates the product's style and basic
    functionality. They express some uncertainty about its ruggedness but
    overall find it suitable for their intended use, resulting in a positive,
    but not top-tier rating.
    Rating (integer): 4
    \n\n
    Review: 'It's a solid backpack at a decent price. Does the job, but nothing
    particularly amazing about it.'
    Analysis: This reflects an average opinion. The backpack is functional and
    fulfills its essential purpose. However, the reviewer finds it unremarkable
    and lacking any standout features deserving of higher praise.
    Rating (integer): 3
    \n\n
    Review: 'The waist belt broke on my first trip! Customer service was unresponsive too. Would not recommend.'
    Analysis: A serious product defect and poor customer service experience naturally warrants the lowest possible rating. The reviewer is extremely unsatisfied with both the product and the company.
    Rating (integer): 1
    \n\n
    Review: 'Love how many pockets and compartments it has. Keeps everything organized on long trips. Durable too!'
    Analysis: The enthusiastic review highlights specific features the user loves (organization and durability), indicating great satisfaction with the product. This justifies the highest rating.
    Rating (integer): 5
    \n\n
    Review: 'The straps are a bit flimsy, and they started digging into my shoulders under heavy loads.'
    Analysis: While not a totally negative review, a significant comfort issue leads the reviewer to rate the product poorly. The straps are a key component of a backpack, and their failure to perform well under load is a major flaw.
    Rating (integer): 1

    Now, here is the review you need to assess:
    \n
    Review: "${review}" \n`;

// Use try/catch to catch (parsing) errors
try {
  // Parse the output for a rating
  const int = /[1-5]/;
  const ratingAsString = llmOutput.match(int)[0];
  // Parse as int
  const ratingAsInt = parseInt(ratingAsString);
  // `checkRating` checks the rating is a number between 1 and 5, since the
  // regEx may catch a number like "100"
  const finalRating = checkRating(ratingAsInt);
} catch (e) {
  console.error('Error', e);
