Unless you're coding a hello-world app, if you aren't using a framework, you are writing your own. If you're working on a 50k+ line frontend app, there's no way you're not gonna come up with a structure, standards, conventions which eventually is gonna become something like the frameworks we already have out there. Frameworks are not built to deal with browser inconsistencies. At least that's not the main selling point, unless you're talking about the jQuery only. You mentioned Angular and Ember which provide a lot more.
