In case anybody else stumbles across this old blog post, I wanted to submit a patch to help with unhandled rejections.
#then
and#catch
each return new Promise instances, so here we actually create two new promises (that aren't assigned). If the argument promise to#makeCancelable
rejects, the promise created by#then
will be an unhandled rejection, which in Node 7 will be an uncaught error.By using the second argument of
#then
to handle rejections instead, we don't need to worry about the runtime finding any unhandled rejections here.
