## Description

ChakraCore is an embeddable JavaScript engine and high-performance scripting runtime. It provides a just-in-time compiler that converts JavaScript source code into optimized machine code during runtime to increase execution speed and throughput.

The engine utilizes a multi-tiered compilation pipeline and tiered machine code generation to balance startup time with execution speed. Memory is managed via a concurrent garbage collector that reclaims unreachable objects on background threads to minimize application pauses.

The project provides capabilities for embedded JavaScript execution and automated memory management within host applications.
