Sort Students by Score

15 minIntermediateJavaScript

Cikgu Rina wants a ranking table for her class quiz. The current code puts the lowest score on top, shuffles students with equal scores unpredictably, and quietly rearranges the original students array that other parts of the app rely on.

JavaScript

sortStudents(students).map((s) => s.name)
// ["Hafiz", "Farid", "Wei Ling", "Arjun", "Aisyah", "Mei"]
//   100      92       92         85       78        9
//   Farid and Wei Ling both have 92 → A–Z by name

Expected order for the sample data

Constraints

Each student is an object like { name: "Arjun", score: 85 }. Return the same objects, re-ordered.
Highest score first. Equal scores → alphabetical by name (A–Z).
Return a new array; the array passed in must keep its original order. An empty list returns [].

Fix sortStudents(list) so it returns a new array of student objects sorted by score (highest first), breaking ties by name A–Z, without changing the original array.

Checks

Highest score first
Equal scores are ordered A–Z
Returns a new array and leaves the original alone
The table shows the ranking
