ProgressEvent

Generated from idl/xhr.webidl when the site was built at 7aa23e2.

ProgressEvent is an interface in idl/xhr.webidl, inheriting Event, exposed in Window, Worker. What it does is on MDN; this page says what niso has of it.

The web features its members belong to, each with its Baseline status on the web and how much of the feature’s WPT suite passes in niso (see Web platform support).

Members the web has, by the BCD keys web-features 3.45.0 lists, that idl/ doesn’t declare. The list is partial: web-features lists only the keys it maps to a feature.
