So at the moment I'm developing a RESTful API for an internal project at work and I'm starting to learn and understand about HTTP status codes.

So I started incorporating proper response HTTP status etc, but my co-workers don't understand what any of it means. They think that just sending a JSON response is enough with any messages should be enough. I think this mindset stems from people who just do simple AJAX calls in JavaScript just to get or store data.

It's these kind of developers that I find are lazy or have no motivation to improve themselves, which is disappointing.
