🐛 Bugreport

I have tried to apply JavaScript compression as per the js_compress config option in hm3.ini but it fails with the following error:

Using yuicompressor:

Sadly you now need to use an ES6 compatible compression tool so yuicompressor or uglifyjs won't work anymore. However uglifyjs.terser should work fine. I will update the sample ini with more accurate examples.

Very well, I'll give uglifyjs.terser a try then.

@jasonmunro I have now installed terser v4.7.0

Can you please let me know which command line parameters to pass in hm3.ini?
