Correct. That is why I agree with this post. The term &quot;full-stack&quot; is meaningless. What people really mean is &quot;frontend&#x2F;backend generalist&quot; which in the current ecosystem means knowing a framework for the frontend and another for the backend. If you go for the true meaning of &quot;full-stack&quot; then no one fits the description because the modern stack is just way too complicated. Just figuring out what the hell your CPU cache lines are doing is already a full-time job in and of itself.
