This is what happens when so many people are using so many frameworks that it becomes a special thing to not use a framework or helper library!
Don't get me wrong, everyone uses libraries in programming. Even in C, for example, I'm importing <windows.h> or <stdio.h>. But, for website building, using JS frameworks and libraries seems to be more common... Likely because many sites need to get up and running as fast and possible and/or are lower-budget projects than say, Oracle Database.
