SQL is the most beautiful programming language. You never have to tell the machine how to do the complex algorithms to filter and transform your data. When have you ever had to write an integer index into something in SQL? Never (unless you were using nonstandard shit like array types which goes against the whole idea of using a relational database). You just describe what you want to happen, and you get it. That's how programming should be.
You can do in 1 line of SQL what it would take a Haskaller a bunch of lenses and monad transformers to do and what it would take Javascript/JSON 100 MB of memory to do.
