You might consider using an ordinary JS object to wrap the Java Promise Object.
Even though the wrapper exists, the indirection should eventually optimize out
(more so than for JSObject.) As far as having more objects about, I think it’s
small relative to other objects in the background
Hi,
For the Vert.x project I've created a simple Promise implementation as
available in a Browser.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise
I've then played with babel to transpile the ES7 async - await to Promises
and I must say that it works
