A new beta of Google’s V8 JavaScript engine is now available.

V8 is a staple in both the Chrome browser and the Node.js JavaScript runtime. WebAsembly is also supported in Mozilla Firefox, Apple Safari, and Microsoft Edge, though those browsers do not use V8.

Future version: New features in Google V8 Version 6.9 beta

The beta of V8 Version 6.9 arrived on August 7, with the production release due in a few weeks in coordination with the planned arrival of the Chrome 69 stable browser. Memory and performance improvements are the focus of the Version 6.9 beta Google’s JavaScript engine.

For memory savings, Version 6.9 offers embedded built-ins for x64-based computers. These are functions shared by all isolates and embedded onto the binary itself instead of being copied onto the JavaScript heap, thus existing in memory only once regardless of how many isolates are running. V8’s designers have seen an average 9 percent reduction of the heap size across the top 10,000 websites on x64 computers. Support for other platforms will follow in later releases.
