Check the Browser compatibility table carefully before using this in production.

The start() property of the PresentationRequest interface returns a Promise that resolves with a PresentationConnection after the user agent prompts the user to select a display and grant permission to use that display.


var promise = presentationRequest.start()
promise.then(function(PresentationConnection) { ... })
       .catch(function(error) { ...})



Return value

A Promise that resolves with a PresentationConnection.
