I question their proficiency with React (for web). There are some abstractions you just have to be aware of. If you're a web developer you have to have a good mental model of the DOM and how web frameworks interact with it ... because even if you work on React exclusively, the React component abstraction is not perfect and the DOM is going to leak through. >Author seems to take for granted that not everyone knows sql. Then ORM is incredibly dangerous for them to use. ORM frameworks are useful but their abstraction of SQL is very leaky. You have to have a reasonable understanding of SQL in order to use an ORM framework effectively, otherwise you will get yourself in trouble. I bet this is where a lot of ORM criticism comes from ... namely developers who don't know SQL and therefore use ORM as crutch when working with a relational database. They can create a very nice object model with an ORM framework that is shit when it comes to the actual queries it generates.
