This is very similar in Rails.
Only in Rails it is far easier to accidentally introduce interfaces that do this: the downside of having a very easy DSL to quickly add relations between records/tables is that people very quickly add relations between records/tables: introduce spaghetti.
And in Rails it is very hard to debug, because ActiveRecord tries hard to be smart, but this "smart" quickly degrades into "black magic" when stuff gets complex (mostly caused by: see above, in my experience).
Edit: currently working on a codebase where 3000ms queries to get 200 items is no exception, where 500+ queries to build a page is common and where, if you change a foo on a bar, suddenly at the other end of the app, your blargs and blazzes start blurping out SQL that used to run 200ms but now adds some wheres and limits and group-bys that make it run over 2000ms. Yay for Rails trying to help!/s

WimLeers
High performance server-side rendering
Compared to solutions based on JSX that exclusively do virtual DOM rendering, Marko has a huge advantage for server-side rendering. When rendering to a virtual DOM tree on the server it’s a two-step process to render HTML:
First pass to produce an entire virtual DOM tree in memory
Second pass to serialize the virtual DOM tree to an HTML string that can then be sent over the wire (this requires traversing the entire tree structure)
In contrast, Marko renders directly to an HTML stream in a single pass. There is no intermediate tree data structure.

WimLeersIf client-side JavaScript isn’t benefiting the user-experience, ask yourself if it’s really necessary. Maybe server-side-rendered HTML would actually be faster. Consider limiting the use of client-side frameworks to pages that absolutely require them. Server-rendering and client-rendering are a disaster if done poorly.
