Hi all. At the moment I am using Google compiler service. However, the Google compiler service creates many lines during compression. Ideally I need one line, like in an obfuscator. An obfuscator, in some cases, is not suitable for me, for several reasons. Tell me who uses which JavaScript Minifier, and which one is used when compressing three.min.js

`three.min.js` is produced with terser. To be more precise with the `@rollup/plugin-terser` npm package.
