WebMIDI

[sy-filis]

Hi there,

Could someone please address an issue with the WebMIDI API types lib.dom.d.ts:14856-15024?

I believe that MIDIInputMap should extend ReadOnlyMap<MIDIInput["id"], MIDIInput> (MDN) and that the forEach method could be removed as part of ReadOnlyMap interface (es2015.iterable.d.ts:119, es2015.collection.d.ts:37). The same situation applies to MIDIOutputMap (MDN).

The second issue concerns constructors for MIDIAccess, MIDIInputMap, MIDIOutputMap, MIDIPort, MIDIInput and MIDIOutput. When attempting to instantiate any of these, I encounter an Uncaught TypeError: Illegal constructor error, although TypeScript indicates it should be permissible.

Thank you.
