DeprecationReportBody.id

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(function(reports, observer) {
  let firstReport = reports[0];
  console.log(firstReport.type); // deprecation
  console.log(firstReport.body.id);
}, options);
