'''Chakra''' was a [[free and open-source]] [[JavaScript engine]] developed by [[Microsoft]] for its [[Microsoft Edge Legacy]] [[web browser]]. It is a [[Fork (software development)|fork]] of the [[Chakra (JScript engine)|same-named JScript engine]] used in [[Internet Explorer]]. As with the [[EdgeHTML]] [[browser engine]], the declared intention was that it would reflect the "Living Web".<ref>{{cite web|title=Targeting Edge vs. Legacy Engines in JsRT APIs|url=https://msdn.microsoft.com/en-us/library/dn903710(v=vs.94).aspx|access-date=10 September 2015}}</ref> The core components of ''Chakra'' were open-sourced as '''ChakraCore'''. In 2021, Microsoft terminated support for the engine, citing its transition to a [[Chromium (web browser)|Chromium]]-based engine for [[Microsoft Edge|Edge]]. Support has been transferred to the community, where it remains inactive.<ref>{{Cite web |title=org/Release 1.12 plan.md at master · chakra-core/org |url=https://github.com/chakra-core/org/blob/master/Release%201.12%20plan.md |access-date=2023-11-17 |website=GitHub |language=en}}</ref><br />

==Standards support==<br />
Chakra supports [[ECMAScript]] 5.1 with partial support for [[ECMAScript]] 2015.<ref>{{cite web|title=Microsoft Edge Platform Status|url=https://dev.modern.ie/platform/status//?filter=f0100001c&search=es6|publisher=Microsoft.com|access-date=10 September 2015}}{{Dead link|date=June 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><br />

==Open sourcing==<br />
Following an initial announcement on December 5, 2015,<ref>{{cite web|url=https://blogs.windows.com/msedgedev/2015/12/05/open-source-chakra-core/|title=Microsoft Edge's JavaScript engine to go open-source|publisher=[[Microsoft]]|access-date=December 8, 2015|date=2015-12-05}}</ref><ref name="ChakraCoreopensourced">[https://www.zdnet.com/article/microsoft-open-sources-its-edge-web-browser-javascript-engine-and-plans-to-port-it-to-linux/ Microsoft open sources Edge web browser's JavaScript engine, plans port to Linux] on [[zdnet.com]] by Steven J. Vaughan-Nichols (on January 13, 2016)</ref> Microsoft open sourced the Chakra engine as ChakraCore, including all the key components of the JavaScript engine powering Microsoft Edge [Legacy] on their GitHub page under the [[MIT License]] on January 13, 2016.<ref name="ChakraCoreopensourced" /><ref>[https://github.com/Microsoft/ChakraCore ChakraCore] on [[github.com]]</ref> ChakraCore is essentially the same as the Chakra engine that powers the [[Microsoft Edge Legacy]] browser, but with platform-agnostic bindings, i.e., without the specific interfaces utilized within the [[Universal Windows Platform apps|Universal Windows App]] platform.<br />
<br />
Microsoft has also created a project on [[GitHub]] that allows [[Node.js]] to use ChakraCore as its JavaScript engine instead of [[V8 (JavaScript engine)|V8]].<ref>[https://github.com/Microsoft/node Node.js enabled for ChakraCore] on github.com</ref><br />
