While Microsoft is in a cloud first era, we would also think the Era of Openness would be an apt name. The company is embracing other platforms. For the most part this means adding services to the likes of Android and iOS. However, Microsoft is also finally backing Linux in a big way and delving into areas of true openness.
“The first experimental implementation of ChakraCore interpreter and runtime on x64 Linux and OS X 10.9+, along with experimental Node.js with ChakraCore (Node-ChakraCore) on x64 Linux. Our development and testing on Linux happens primarily on Ubuntu 16.04 LTS, but the support should easily translate to other modern Linux distributions.”
Of course, Microsoft's Era of Openness is more about enticing developers to the Windows platform. Running ChakraCore on OS X and/or Linux gives developers tools to build cross-platform applications that will also work on Windows.
