Do you actually believe that's true? I can understand if this is just a knee-jerk comment that you haven't put thought into, but if it isn't that, I truly hate your kind of thinking.
While I'm not a fan of modern front-end programming, I do appreciate the sheer amount of knowledge and tedium involved in making that 'read/write DB operation' actually work in the context of the demands of modern front-end development, and I despise those who pretend it's trivial.
Is it different from the kind of knowledge necessary for picking the right algorithm? sure! Is it inferior (by whatever definition that self-servingly serves), and does it involve 'knowing nothing'? Far from it. Knowing what's necessary for a lot of front-end work is far from trivial, and while I dislike it, pretending it involves no knowledge or expertise is 100% pure bullshit.
