For projects where upstream does _not_ use YUI-compressor themselves, I 
recommend to immediately switch to uglify-js 3.x.

For projects where upstream _does_ use YUI-compressor, I suggest to 
cautiously try switch, but then make sure to test at least once the 
resulting code by testing the minified files in a web browser: Maybe 
upstream (even unknowingly) rely on specific behaviour/flaws of 
YUI-compressor.

Beware that YUI-compressor also supports compressing CSS files.  I 
recomend replacing that with sassc: Sass takes Sass code as input 
(serialized as either SASS or SCSS), but since SCSS is a strict superset 
of CSS it can take CSS as input as well.

I do *not* recommend replacing JS compressor with Terser: I highly doubt 
that YIU-compressor supports newer ES6 code as input which would be a 
reason to use Terser instead of Uglify-js, and Terser is not up-to-date.

I do *not* recommend replacing CSS compressor with LESS.js: Unlike SCSS, 
the LESS format is *not* a strict superset.

I do *not* recommend replacing CSS compressor with PostCSS: PostCSS can 
do lots of things, raising the risk of doing some things wrong.
