Let's look at some history:
But Ryan Dahl let the front-end developer be a full-stack developer by making Node.js
Starting from 2017-2018 people start choosing a path to follow, like Angular developer, React Developer and so on.
Also me, I'm known as Angular developer, That's the main framework that I work with but you need also to master other Frameworks if you want to be laways fresh.
Following everything is the perfect option to lose focus. for me, I'm really aware of what I should consume to prevent the distraction, and also I create a routine to keep up with what should I know.
