The Windows 10 Technical Preview brings key advances to 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. As with all previous releases of Chakra in IE9, IE10 and IE11, this release is a significant step forward to create a JavaScript engine that is 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. This post details some of these key performance improvements.

It still gives me a nice tingly feeling every time I see MS talk about standards compliance in reference to IE. Such a different world from the 90's and 00's; we still have cross-browser compatibility issues, but at least moving forward the baseline functionality will be much more uniform. I wonder if Microsoft's choice to build WinJS for Windows Store applications (and now the web) influenced this strive for compatibility?
