Chakra powers Universal Windows applications across all form factors supporting Windows 10. It is used by TypeScript and runs Node.js with it, to make Node.js available on a new IoT platform: Windows 10 IoT Core.
Chakra supports most of the ECMAScript 2015 features, and it supports some future ECMAScript proposals, such as Async Functions. It supports asm.js and is a key player in helping evolve WebAssembly and its associated infrastructure.
Further, ChakraCore will support a new set of modern diagnostic APIs which could be standardized or made interoperable across different implementations.
"Releasing Chakra as open source paves the way for adoption by other software products and projects across the ecosystem, from the cloud to desktop to IoT," said Bill Weinberg, president and principal analyst, LinuxPundit.
