DeprecationReportBody: anticipatedRemoval property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Note: This feature is available in Web Workers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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.

Value

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

Examples

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