Thx Michael, ya are totally right, but this is just a pseudo-code sample to show how it's easier to craft async code in node.js :-)

I also loves golang concurrency design, but node.js is pretty handy to write microservices these days. You probably will find some messy legacy code only with callbacks/promise hell etc.., but you also find shit code in any language, so it's not node.js fault. It's pretty straightforward to write elegant async/concurrent/parallel code with node.js using generators and async/await post( 'api/v1/orders' , async (ctx) => { try { // for me one app is fast when handling IO bound, like this await Promise .all([ Order.create(ctx.body), Invoice.update(ctx.body), Tracking.updateWithOrder(ctx.body), Event.traceOk(ctx.body) ]) ctx.body = {created: true } } catch (err) { ctx.throw( 422 , err) await Event.traceErr(ctx.body) } })
