Minified JavaScript

How it works

Variable names are not renamed, so the output stays readable and debuggable.
Comments are removed and indentation collapsed; line breaks are kept by default so ASI behaviour is unchanged.
Strings, template literals and regular expressions are copied byte-for-byte.
