What’s new in V8/JavaScript

What exciting things happened in the JavaScript language and the V8 engine in 2019? Shu and Leszek take a tour of some new features and improvements. For JavaScript, learn about new syntax, like optional chaining and nullish coalescing, that make expressing common patterns a breeze, as well as the powerful new weak references that may help plug memory leaks. For V8, learn how the engine got faster with streaming parsing and slimmer with pointer compression.
