Review Summary

Decision: REQUEST_CHANGES — there’s a critical blocker in query parameter handling.

Critical issue to fix

• File: src/createServer.js, around line 19
  • What’s wrong: When a query key appears multiple times, the code assigns an array to query[key]. The requirement states all query values must be strings, and if a key repeats, only a single string should be included (last occurrence wins).
  • Why it’s a problem: This violates the core requirement “query parameter values must be strings,” and will cause incorrect output for duplicate keys.
  • How to fix: When iterating over URLSearchParams, always assign a string and overwrite previous values so the last one wins. For example, use for (const [k, v] of searchParams) { query[k] = String(v); } and avoid collecting arrays like query[k] = [...(query[k] || []), v]. Alternatively, use searchParams.getAll(k) only if you then take the last item as a string: query[k] = arr[arr.length - 1].

What’s good

• Path splitting, filtering empty segments, handling multiple slashes, response structure, and JSON formatting all look correct. Great job on these parts.

Please address the query handling so that duplicate keys result in a single string value (last occurrence). Once that’s fixed, this should be ready to approve. Keep up the good work!

The requirements specify that query parameter values must be strings, and if a key appears multiple times, only a single string value should be included (e.g., last occurrence wins). This line assigns an array if there are multiple values, which violates the requirements. You should only assign a string value for each key, not an array.

Review Summary

Decision: REQUEST_CHANGES

Your server is very close and well-implemented overall, but there’s one critical blocker to meet the requirements.

Critical issue to fix (blocks requirements):

• Repeated query key handling returns the first value instead of the last.
  • Location: src/createServer.js (look where you build the query object from searchParams)
  • Why it’s wrong: The requirement states that for repeated keys (e.g., ?a=1&a=2), you must return the last value as a string. Using searchParams.get(key) always returns the first occurrence, which violates this rule.
  • How to fix: Iterate over all entries and assign in order so the last occurrence wins, e.g.:
    • const query = {}; for (const [key, value] of searchParams) { query[key] = value; }
    • Alternatively, use const values = searchParams.getAll(key); query[key] = values[values.length - 1];

What you did well:

• Correct URL parsing with URL/URLSearchParams.
• Proper handling of path segments and multiple slashes, and correct JSON response with parts and query.
• Clean, robust code that handles empty paths and missing queries.

Once you adjust the repeated key handling so the last value is used, your solution should fully comply. Great work—this is a small, targeted change to complete the task!

The current approach to extracting query parameters uses searchParams.get(current), which always returns the first value for a key. The requirements specify that if a query parameter appears multiple times, only the last value should be used (as a string). To fix this, consider iterating over all entries in searchParams and assigning each key-value pair to the result object, so the last occurrence wins. For example:

const query = {};
for (const [key, value] of searchParams) {
  query[key] = value;
}

This will ensure that for repeated keys, the last value is used, matching the requirements.

Review Summary

Educational approval: You’ve done a strong job overall—clean server setup, correct JSON shape, proper Content-Type, robust path splitting (handles multiple/leading/trailing slashes), and solid use of URL/URLSearchParams.

Critical issue to address (Checklist 3.2):

• Location: src/createServer.js (where you build searchParamsResult)
• Issue: Using searchParams.get(current) returns the first value for repeated keys (e.g., ?a=1&a=2 yields a: "1"), but the requirement specifies the last value must win.
• Why: URLSearchParams#get always returns the first occurrence. The spec for this task requires last occurrence to be used.
• How to fix (hint): Iterate over all entries and assign in order so later values overwrite earlier ones. For example:

  const query = {};
  for (const [key, value] of searchParams) {
    query[key] = value; // last one wins
  }

Minor note: Consider a brief comment explaining why “last value wins” is intentional for future readers.

You’re very close—great progress! Apply the small query handling tweak and you should be fully compliant.

The construction of searchParamsResult uses searchParams.get(current), which always returns the first value for a repeated key. The requirements specify that for repeated keys (e.g., ?a=1&a=2), the last value should be used. Consider iterating over all entries and assigning values in order so the last occurrence wins, e.g.,

const query = {};
for (const [key, value] of searchParams) {
  query[key] = value;
}

This will ensure that the last value for each key is used, as required by the checklist item 3.2.
