💬 Code Comments

Good Comments

// calculateRateLimit returns the rate limit for a user based on their tier.
// Premium users get 1000 req/min, free users get 100 req/min.
func calculateRateLimit(tier UserTier) int {
    // ...
}

/**
 * Fetches user data from the API with automatic retry.
 * @param userId - The unique identifier of the user
 * @param options - Optional configuration
 * @returns The user object or null if not found
 * @throws {NetworkError} When the API is unreachable
 */
async function fetchUser(userId: string, options?: FetchOptions): Promise<User | null> {
    // ...
}

Avoid These

// ❌ Obvious comments
i++ // increment i

// ❌ Outdated comments
// Returns user by email  <- but function uses ID now
func GetUserByID(id string) *User
