ChakraCore 1.4.0 is the very first release by Microsoft that brings the experimental support for the WebAssembly portable core format. This development is aimed to expand the core of Chakra engine across browsers built by Apple, Google and Mozilla and receive support from the WebAssembly community.
Microsoft revealed its interest towards WebAssembly in October. “We have been hard at work developing support for WebAssembly in Microsoft Edge at the open source ChakraCore project repo. Microsoft Edge and ChakraCore are close to shipping the browser preview,” Microsoft Chakra’s programme manager Limin Zhu had written in a blog post.
Apart from the significant upgrade with the WebAssembly support, Microsoft has brought JIT to Linux and macOS and out of process JIT support for its Edge. Developers can leverage this tweak to run multiple Chakra runtime clients.
