If programmers were just more disciplined, more professional, they’d write better software. Requiring programmers who have access to computers to recall and follow repetitive information processes is wasteful, when the computer can do that. Back in my day, everybody knew “no Markdown around town” and “don’t code in an IDE after Labour Day”, but now the kids do whatever they want. You don’t need React Native to write good front-end code, just JQuery and some discipline. You don’t need JQuery…But along with the term of experience goes the breadth.
