As a young'un myself (u/g senior), I think the more disturbing thing is that I see stuff that's missing (from front-end alone: ES5, ES7, Babel, Selenium, service workers, deferred dependencies, accessibility, Backbone, UI/UX, polyfills, and generally YAGNI/KISS to remind people that there are few things on the web that actually need to be SPAs).

Fortunately I have no desire to do front-end work.
