Minifying / Minification / Minified
Minifying means removing all the unnecessary characters in a file to make it the absolutely smallest possible version it can me. It is often compared to compiling but strictly speaking is an entirely different thing. To see some seriously minified code just look at Google’s source code of their main home page.
💎 Minification has become far less necessary now that offline-first has become a thing. In fact, some argue against it for the layer of unnecessary complexity it adds now that any efficiency gains are minimal when combined with an offline-first approach — as everyone should.
