Unnecessary use of jQuery global

Created by: thheller

It seems to me that bootstrap still has an artificial dependency on the jQuery global that seems unnecessary.

At the top of the file jquery is imported but then the jQuery global is used. https://github.com/twbs/bootstrap/blob/a4667be152a3a4fed4e42f2a9efbf831bb5946b6/js/src/index.js#L1

But then the "check" uses the global https://github.com/twbs/bootstrap/blob/a4667be152a3a4fed4e42f2a9efbf831bb5946b6/js/src/index.js#L21-L32

This pattern is repeated in other files as well, the top imports jquery as $ but then uses jQuery in code. Should it not use $ instead?

I'm asking from a build tool perspective which wouldn't have any issues if the imported object was used instead of the global?
