Read first Task 19

JSON.stringify writes, JSON.parse reads — the language of APIs.

Definition and example

JSON is the focus of this lesson. JSON.stringify writes, JSON.parse reads — the language of APIs. The task asks you to apply that idea in a small example: Which turns an object into text. Before you run the code, predict what should happen. Then Inspect the browser output and the value your code produces and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.
