I thought eBay and PayPal were using Dust for their NodeJS stack and then I came across the "Async Fragments: Rediscovering Progressive HTML Rendering with Marko" (see http://calendar.perfplanet.com/2014/async-fragments-rediscovering-progressive-html-rendering-with-marko/) post on PerfPlanet. It looks like eBay is switching to a new templating language that I had not heard of called Marko (see https://github.com/raptorjs/marko).
My team has been using Dust for the past 3mo and have been relatively satisfied but we have ran into many limitations (poor error reporting/debugging, issues with helpers, difficulties using the client, etc.). I have been experimenting with Marko and it looks awesome (clean HTML syntax, async rendering, Node.js module as output, to name a few...). It is kind of like Angular templating, but faster and works on the server and client.
My questions are: Are there other companies using Marko? Does anyone have experience using Marko in their projects and, if so, what are your thoughts?
