The toJSON() method of the DeprecationReportBody interface is a serializer, and returns a JSON representation of the InterventionReportBody object.

None.

A JSON object that is the serialization of the DeprecationReportBody object.

In this example we create a new ReportingObserver to observe deprecation reports, then return a JSON representation of the first entry.

let options = {
  types: ["deprecation"],
  buffered: true,
};

let observer = new ReportingObserver((reports, observer) => {
  let firstReport = reports[0];
  console.log(firstReport.toJSON());
}, options);
