To that point, it's interesting how many claim that Backbone is yesterday's tech and that we are now 2 or 3 iterations of javascript frameworks past Backbone, yet most of these large sites are still using Backbone! It's possible that a lot of the sites would use something other than Backbone if they were built today, but it's clear that Backbone will be around for some time.

Yesterday or not, Backbone works. Loads fast. And is dead simple to use.

Probably not in modern web companies, but there are still COBOL stacks around.
