But what if there isn't a single cohesive team developing the website? There are no globally established practices for CSS name-spacing and there are multiple ways to do it (based on what tradeoffs you're willing to make). See font-awesome for an example of what I mean by library (yes, they prefix everything with `fa-` which is fine until the bootstrap team comes up with a FizzActivity widget in bootstrap, which you wont be able to use together with fontawesome) What happens if two developers namespace their class in the same way in JS? Well, with CommonJS this is pretty much impossible (import by path), and even without CommonJS there is no incentive to do it as you can easily pick a huge namespace without it affecting anyone. Just adding `var shortName = long.namespace.containing.shortName;` fixes the long name without that short name having effects anywhere else in the code or any of the inner functions (components) you may call, because... lexical scope. And sure, we can hand-code everything in assembly too - after all thats what compilers do anyway. But that doesn't mean that the higher level language has all the problems that assembly has. A tool like this can do a lot of the job for you, by generating unique names and letting you refer to them via any (variable) name you like.
