> There was a time when structure, layout and logic were more cleanly separated. Yes, and what many developers started to realize is that this separation is not very useful (at least for proper web applications, as opposed to websites with mostly static content). Conversely, separating the building blocks of application into components where structure, layout and logic commingle is very useful. I realize not all developers agree with eschewing structure/styling/logic separation. But many do and it's important to realize that they do so consciously and not because they don't know what they're doing. Angular was one of the first (perhaps the first, not sure) libraries to move towards this direction. It brought a lot of accidental complexity with it, which is understandable as these concepts were only starting to be fleshed out in the web world.
