## General improvements
## Changes to code extraction
* The extractor now supports additional [Flow](https://flow.org/) syntax.
* The extractor now supports [Nullish Coalescing](https://github.com/tc39/proposal-nullish-coalescing) expressions.
* The TypeScript extractor now handles the control-flow of logical operators and destructuring assignments more accurately.
