WinJS.Promise.as function

Returns a promise. If the object is already a Promise it is returned; otherwise the object is wrapped in a Promise.

You can use this function when you need to treat a non-Promise object like a Promise, for example when you are calling a function that expects a promise, but already have the value needed rather than needing to get it asynchronously.

• value
  Type: Object
