Microsoft starts to open source its JavaScript engine Chakra

Microsoft today announced plans to open source the core components of Chakra, the company’s JavaScript engine that’s used in Microsoft Edge and Internet Explorer. The project, dubbed ChakraCore, will be released on GitHub in January (although initially it will be Windows-only).

Aside from powering Microsoft’s browsers, Chakra also helps power Azure DocumentDB, Cortana, Outlook.com, TypeScript, Node.js in Windows 10 IoT Core, as well as universal Windows 10 applications across Xbox consoles, smartphones, and PCs.
