Well my litmus test regarding outdated way of doing stuff is the answer of the question "If I start a new project today, would I use 'x'?". Answer "no" means the technology is fading even for simple use cases. Example, 'x' and 'No'-answer : - jQuery / prototypejs / etc... - Backbone - CoffeeScript - Perl, SVN, Java Applets :D On the other hand you still have 'Yes'-es for some old tech-stack, since it is still acceptable to do a task with old technology. Example, 'x' and 'Yes'-answer : - Form + POST requests / No javascript - Pure CSS ( no SCSS, etc... ) - Handlebars, instead of React / Vue / you name it
