## Changes to code extraction

24+
* Destructuring assignments are now modeled more precisely, which fixes both false-negative and false-positive results for the rules
25+
"Missing variable declaration" and "Useless assignment to local variable" in certain corner cases.
26+
* The TypeScript compiler is now bundled with the distribution, and no longer needs to be installed manually.
27+
Should the compiler version need to be overridden, set the `SEMMLE_TYPESCRIPT_HOME` environment variable to
28+
point to an installation of the `typescript` NPM package.

# JavaScript extractor
2+
3+
This directory contains the source code of the JavaScript extractor. The extractor depends on various libraries that are not currently bundled with the source code, so at present it cannot be built in isolation.
4+
5+
The extractor consists of a parser for the latest version of ECMAScript, including a few proposed and historic extensions (see `src/com/semmle/jcorn`), classes for representing JavaScript and TypeScript ASTs (`src/com/semmle/js/ast` and `src/com/semmle/ts/ast`), and various other bits of functionality. Historically, the main entry point of the JavaScript extractor has been `com.semmle.js.extractor.Main`. However, this class is slowly being phased out in favour of `com.semmle.js.extractor.AutoBuild`, which is the entry point used by LGTM.
6+
7+
## License
8+
9+
Like the LGTM queries, the JavaScript extractor is licensed under [Apache License 2.0](LICENSE) by [Semmle](https://semmle.com).
