What this example teaches
Performance
Output
MongoDB returns matching documents or grouped metrics for a backend data access layer.
Line-by-line explanation
- Line 1 sets up the Performance example: db.orders.find({.
- Line 2 adds one required part of the working pattern: status: "paid",.
- Line 3 adds one required part of the working pattern: total: { $gte: 104 }.
- Line 4 adds one required part of the working pattern: }).sort({ total: -1 }).
Why this example is useful
This example is useful because it isolates performance without surrounding noise, so you can see the idea clearly.
Where it is used in real projects
Performance appears in real MongoDB work when a feature needs a clear pattern that can be reviewed and changed safely.
Beginner variation
Change one label, value or condition in the Performance example and run it again.
Advanced variation
Combine Performance with validation, error handling or reusable structure.
