good to know. also, the previous benchmark was misleading, because terser
didn’t mangle by default [1]. with mangling, its performance is inline:
```shell
npm install google-closure-compiler terser uglifyjs-lite
curl -O https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.js
<https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.js>
npx google-closure-compiler jquery.js > jquery.min.google
<http://jquery.min.google/>-closure-compiler.js 2>/dev/null
npx uglifyjs-lite jquery.js > jquery.min.uglifyjs-lite.js 2>/dev/null
npx terser jquery.js -m > jquery.min.terser-mangled.js
npx terser jquery.js -c -m > jquery.min.terser-compressed-mangled.js 2>/dev/null
npx terser jquery.js -c -m --mangle-props >
jquery.min.terser-compressed-props-mangled.js 2>/dev/null
ls -lS jquery.*
