Lesson 6 — Working with JSON
Round trip: object → text → object
To send data over the network or save it in a file, you serialize it — turn it into text — with JSON.stringify. The other side deserializes it back with JSON.parse. Numbers, strings, arrays and nested objects all survive the trip.
JSON.stringify({ a: 1 }); // '{"a":1}'
Why it matters: this round trip happens on every API call and every config file your server reads.
