It’s true it happens for other areas too. But I think it might be true that frontend is often viewed as “the easy” part by other devs. Especially older backend devs seem to think it’s all super easy. At least in my experience.
And that businesses try to push for all devs be full stack doesn’t help.
It’s definitely not all. My current team definitely has respect for all that special tooling / ux stuff I’m doing. Especially since nobody was able to do it before I was hired.
But I also had the experience that older Backend devs don’t take it seriously. My guess would that those stoped learning about frontend tech in the late 90s and it’s a case of not knowing what you don’t know.
