This is poor advice these days... most tooling is/has moved towards module patterns that isolate code based on modules. Most browsers even have built in support for javascript modules at this point, and there are ever more sites that publish the likes of npm as ecmascript modules for easier use in that fashion.
Currently, these are a bit slower than what bundlers can do, but is definitely the way forward... this advice seems like a flashback to pre-2010 advice for JavaScript. This really started to change in 2010-2012 with Browserify with 6to5 and later Webpack and Babel (renamed 6to5). Now there's more options including Parcel, TypeScript, Babel, Webpack and others.
