-## JSON.stringify
-
-Some tests in this workshop read structured values from the terminal output.
-To do that, we use `JSON.stringify(...)` to convert objects into strings that
-can be printed and parsed reliably.
-
-```ts
-const result = { greeting: 'Hello', count: 3 }
-console.log('Results:', JSON.stringify(result))
-```
-
-`JSON.stringify` turns JavaScript values into a JSON string so the test can
-compare exact results.
