We can use getter for feature detection. For example:
var hasOneTimeOnly = false, hasAutoRevoke = false;
var o = {};
Object.defineProperty(o, "oneTimeOnly", { get: function(){ hasOneTimeOnly =
true; return false; } });
Object.defineProperty(o, "autoRevoke", { get: function(){ hasAutoRevoke = true;
return false; } });
URL.createObjectURL(new Blob(), o); // getter will be called if supported
