This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The MIDIOutputMap read-only interface of the Web MIDI API provides a Map-like interface to the currently available MIDI output ports. Although it works like a map, because it is read-only, it does not contain clear(), delete(), or set() functions.
