The Inner Workings of the Chakra Javascript Engine

Explore the inner workings of Microsoft's Chakra Javascript engine in this 52-minute conference talk from GOTO Aarhus 2012. Dive into the project's goals, status, and development path as presented by Steve Lucco, Chief Architect at Microsoft. Learn about design principles, JIT security and hardening, ECMAScript compliance, and balanced performance optimization for page load and app start-up times. Discover Chakra's garbage collector, interactive response capabilities, and optimistic profile-based JIT. Examine type-specialized integer and float math, fast property access, and gain insights into the ongoing development efforts for this engine used in Internet Explorer 9 and 10.
