The “universal” label that has been slapped on to it is superfluous, but it does have its merits. Now that we have a commonly known term to refer to environment agnostic JavaScript code, it allows library authors to list it as a feature and be fashionable doing it. I’m happy with the term “universal” being fashionable because it makes developers think about their dependencies on the runtime environment. In the end this will help the JavaScript ecosystem mature and allow libraries to be used everywhere.
