Great news: Microsoft is adding asm.js to the Chakra JavaScript engine in Windows 10

asm js

Microsoft IE team today announced that they are adding asm.js support to Chakra JavaScript engine in Windows 10. Support for asm.js has been one of the top 10 most-requested items at the IE Suggestion Box on UserVoice and now Microsoft is fulfilling user request.

Delivering an interoperable & spec compliant JavaScript engine with the capabilities and performance for modern experiences has been a key goal for us since the inception of Chakra. Bringing near-native performance for JavaScript code execution is a part of the same. We recently shared the details of some of the work we’ve done in Windows 10 to boost JavaScript execution speed in the Chakra engine.

Over the last few months we’ve taken a close look at asm.js as a technology, related technologies, and what they entail for the Web at large. While challenging to write by hand, asm.js is leveraged principally by transpiling C/C++ code to run on the Web platform, utilizing technologies such as WebGL and Web Audio. Asm.js is a clear step towards enabling near-native performance for the Web platform, which is why we’re excited to bring it to Chakra in an upcoming release.
