- Performance evaluation. Without minification and gzip, you can't always make accurate decisions regarding filesize changes, or do reasonable network speed testing locally.
- Cache-busting. By compiling your files and saving them with unique names, you're removing the need to clear the browser cache when testing on mobile devices and in older IE.
- Catching bugs.
- This is rarer now than it used to be, but uglify has historically created occasional issues in IE8. Better to catch them locally than on integration.
- Running in production mode exposes problems related to explicit filenames, since a production deploy can change filenames and break related code.
