 We have lots of tooling dedicated to ensuring consistent code. We use [Prettier](https://prettier.io/), [TypeScript](https://www.typescriptlang.org/), and [ESLint](https://eslint.org/) to help us deliver quality code. These are checked by the build system and should be enforced at commit time by [Husky](https://typicode.github.io/husky/#/).
 
-Most packages are written in TypeScript, while a few plain Javascript still linger. You can generally use modern Javascript when modifying Turf itself as all exported code is transpiled to (currently es2017).
+Packages are written in TypeScript. You can generally use modern TypeScript when modifying Turf itself as all exported code is transpiled to a more compatible subset (currently es2017).
 
 Code for consumption by browsers is transpiled by Babel as described in the README.
