Open sourcing

Following an initial announcement on December 5, 2015,Microsoft open sources Edge web browser's JavaScript engine, plans port to Linux

Vaughan-Nichols (on January 13, 2016) Microsoft open sourced the Chakra engine as ChakraCore, including all the key components of the JavaScript engine powering Microsoft Edge on their GitHub page under the MIT License on January 13, 2016.

Microsoft has also created a project on GitHub that allows Node.js to use ChakraCore as its JavaScript engine instead of V8.Node.js enabled for ChakraCore
