Microsoft Details Improvements In Chakra JavaScript Engine Delivered As Part Of Internet Explorer In Windows 10 Preview

Yesterday, Microsoft detailed about the HTTP/2 implementation in Internet Explorer included in Windows 10 Technical Preview. Today, they detailed the improvements they have made in Chakra, the JavaScript engine that powers Internet Explorer and store based Web apps across a whole range of Windows devices – phones, tablets, 2-in-1’s, PC’s and Xbox. This release includes highly interoperable, spec compliant, secure and delivers great performance. Chakra now has a highly streamlined execution pipeline to deliver faster startup, supports various new and augmented optimizations in Chakra’s Just-in-Time (JIT) compiler to increase script execution throughput, and has an enhanced Garbage Collection (GC) subsystem to deliver better UI responsiveness for apps and sites.

Without making any changes to your app or site code, these optimizations will allow your apps and sites to have a faster startup by utilizing Chakra’s streamlined execution pipeline that now supports a Simple JIT and multiple background JIT threads, have increased execution throughput by utilizing Chakra’s more efficient type, inlining and auto-typed array optimizations, and have improved UI responsiveness due to a more parallelized GC. Given that performance is a never ending pursuit, we remain committed to refining these optimizations, improving Chakra’s performance further and are excited for what’s to come.
