A string representing the given date-time in the Temporal.PlainDateTime.from() function as the reviver of JSON.parse().
const dt = Temporal.PlainDateTime.from({ year: 2021, month: 8, day: 1 });
const dtStr = dt.toJSON(); / '2021-08-01T00:00:00'
const dt2 = Temporal.PlainDateTime.from(dtStr);
This example shows how Temporal.PlainDateTime can be serialized as JSON without extra effort, and how to parse it back.
const dt = Temporal.PlainDateTime.from({ year: 2021, month: 8, day: 1 });
const jsonStr = JSON.stringify({ nextBilling: dt }); / '{"nextBilling":"2021-08-01T00:00:00"}'
const obj = JSON.parse(jsonStr, (key, value) => {
if (key === "nextBilling") {
return Temporal.PlainDateTime.from(value);
}
return value;
});
