You can let TypeScript compile as little as possible by knowing what the baseline supportfor ECMAScript features are available in your node version

You can also usehttps://github.com/tsconfig/bases/ to findtsconfig.jsons to extend, simplifying your own JSON files to just the options for your project.

To update this file, you can usenode.green to map to the different options inmicrosoft/typescript@src/lib

Note:module is set tonodenext to allowrequire("esm"). After TypeScript 5.9 is released, it is recommended to set it tonode20 instead.

Note: Due to a V8 bug, one rarely-used ES2020 feature was incorrectly implemented in Node <16.3.0 - "spread parameters after optional chaining"; seeissue 46325. If you use this feature and need to support versions of Node before 16.3.0, you may need to droptarget toES2019.

Note: Due to a V8 bug, one rarely-used ES2020 feature was incorrectly implemented in all releases of Node 14 - "spread parameters after optional chaining"; seeissue 46325. If you use this feature, you may need to droptarget toES2019.
