Open-source JavaScript engine developed by Microsoft
This article is about the JavaScript engine used in Microsoft Edge Legacy. For the engine of Internet Explorer, see Chakra (JScript engine). For other uses, see Chakra (disambiguation).
Following an initial announcement on December 5, 2015,[5][6] 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.[6][7] ChakraCore is essentially the same as the Chakra engine that powers the Microsoft Edge browser, but with platform-agnostic bindings, i.e. without the specific interfaces utilised within the Universal Windows App platform.
Microsoft has also created a project on GitHub that allows Node.js to use ChakraCore as its JavaScript engine instead of V8.[8]
