"architectural style" for what you try to actually understand what REST means that sort of is the key to everything else so, what is an architectural style and what does that means how that affects us ? so, architecture is obviously referring to your software architecture, your stack, how you put your systems together all those kinds of things, but what is a "style", exactly ? well, when I think about REST, i like to think about impressionism and I don't know why I think about impressionism because I know nothing about painting [laughs] at all when I'm thinking about REST
