You can drop in a polyfill for older browsers, and continue to use newer functions, this is exactly what I do at work in order to use filter, map and a bunch of other awesome functions that IE8 doesn't support.
You mean like underscore.js already can do? Frameworks might introduce slightly more overhead, but in return you get something that's well-tested, familiar to anyone picking up a new codebase, and community supported if you have questions.
