The id read-only property of the DeprecationReportBody interface returns a string representing the feature or API that is deprecated. This can be used to group or count related reports.


A string.


In this example we create a new ReportingObserver to observe deprecation reports, then print the value of id to the console.

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

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