ChakraCorea

ChakraCorea is a JavaScript rendering engine developed by Microsoft. It was designed to provide a high-performance JavaScript and WebAssembly execution environment for applications. ChakraCore is a fork of the Chakra JavaScript engine, which was originally developed for Internet Explorer. The engine is notable for its Just-In-Time (JIT) compilation capabilities, which allow for faster execution of JavaScript code by compiling it to native machine code during runtime.

Microsoft utilized ChakraCore as the JavaScript engine for the EdgeHTML engine in the original Microsoft Edge browser. It was also used in various other Microsoft products and services. The goal behind ChakraCore was to offer a more portable and embeddable version of the Chakra engine, enabling developers to integrate its performance benefits into their own applications, services, and even other browsers. This portability was a key aspect of its design, allowing it to be used outside of a full browser environment.

In 2018, Microsoft announced its transition to the Chromium open-source project for the next generation of Microsoft Edge. As a result, ChakraCore is no longer the primary JavaScript engine for Microsoft's flagship browser. However, its development and availability as an open-source project continue, allowing it to be explored and used by developers for various purposes, especially in scenarios where a robust and performant JavaScript engine is required. The engine's architecture and performance optimizations have contributed to the broader understanding and advancement of JavaScript execution technologies.
