Really? It just looks compact and efficient to me.

  "Compact" (abbreviated) names are negligibly more efficient when machines read them, and they're wildly less efficient when humans read them. Code is read many more times than it's written, so it doesn't make sense to optimize for fewer keystrokes when typing the code. This is especially true with modern IDEs that autocomplete everything.

      Post-processors do that much better than a human and can also tree-shake. There's no reason for a human to do it.
