Is adding to the Global Namespace considered bad?


Im wanting to load some modules one time rather than have to keep loading the on several view pages.

  1. If i add them to the global namespace in app.js is this considered bad practice?
  2. is it more performant to load it on each page vs 1 time on app.js?


depending on how many you put in app.js, it may slowdown App start up, but according to me its the best way to include it there(app.js) as it is global.
