DeprecationReportBody.anticipatedRemoval

The anticipatedRemoval read-only property of the DeprecationReportBody interface returns the date that the browser version which removes the feature will ship. This value can be used to prioritize warnings. If this property returns null because the date is unknown, then the deprecation should be considered low priority.

A date object, or null if the date is not known.

In this example we create a new ReportingObserver to observe deprecation reports, then print the value of anticipatedRemoval 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.anticipatedRemoval);
}, options);
