V8 version 8.0 adds performance improvements and optional chaining

Version 8.0 of Google’s open source JavaScript engine V8 has arrived. This poetic release of V8 v8 not only has a nice ring to it, but adds some performance improvements, bug fixes and the ECMAScript language features optional chaining and nullish coalescing.
In a blog post, the V8 developers have announced the release of version 8.0.
V8 is an open source JavaScript and WebAssembly engine that was first released by Google in 2008 and is written in C++. The cross-platform engine can run standalone or embedded into a C++ application.

Version 8.0 will be officially available when it ships with the stable version of Chrome 80, planned to be released in several weeks. If you want to try out the new features sooner, you can either use git checkout -b 8.0 -t branch-heads/8.0
, which requires an active V8 checkout, or subscribe to the Chrome Beta channel.
V8’s Twitter followers are excited about v8, so let’s take a look at the new features!
V8 hits its long-awaited v8.0, now with optional chaining, nullish coalescing, faster higher-order builtins — oh and 40% less memory use thanks to pointer compression, no big deal.
