The variable "elements" as written "elements = getElements()," in the MdTabsController is no longer needed. That is, it is defined, initialized and updated in the MdTabsController controller, but is no longer used because each subroutine function calls its own "elements" variable anyway. Looks to be leftover code, but of coarse, that is for you guys to decide. This is just a heads up that there is a confusing use of "elements" here, nothing more.

A GitHub link to the source where that variable is defined would be very helpful.

It looks like the variable in question is https://github.com/angular/material/blob/v1.1.10/src/components/tabs/js/tabsController.js#L14.

It does look like all of the references are now using getElements() instead of using the controller scoped elements variable.

[Splaktar]

It looks like the big shift to using calls to getElements() instead of the elements variable came as part of 77958a1 (PR #8496) which was in v1.1.0. It was a performance improvement.

PR #11379 submitted to address this.
