Description:
The GetAllMentors function in Backend/controllers/mentor.controller.js (approximately 150 lines) manages query parsing, filtering, population, rating calculation, sorting, and response formatting. This overloads a single function with multiple responsibilities, making it prone to bugs and hard to maintain.
Proposed Solution:
Break into smaller functions: parseMentorFilters, fetchMentorProfiles, calculateMentorRatings, and sortMentors. Use a service layer for rating calculations to decouple logic.
Result:
Enhanced readability, easier unit testing of individual parts, and reduced function complexity, lowering the LOC per function and improving error isolation.
