Stateless functions still deal with state, they just don’t hold onto it. Without state to mutate, a so-called stateless function doesn’t do anything.
In declarative languages, your state is the sum of everything you’ve declared. You don’t query results out of thin air. Computational results logically conclude from everything you set up.
HTML ““has state””, as in it has a DOM, but it doesn’t do anything with it. You don’t mutate the DOM after it’s built, or query the DOM to compute results that weren’t trivially evident from the state you declared.
You can do those things with JavaScript. But all that proves is JavaScript is a programming language, and HTML is just a data format it can interact with.
Programming is the art of juggling of state and control flow
Sure, stateless functions deal with and impact state in some way. If that’s what you meant by your previous comment, that’s fine, but that’s honestly not what would typically be meant by “juggling” state.
The part about declarative languages has nothing to do with state. Declarative languages do not give the programmer control over flow, the other part of your definition.
Learn Lisp, and you will never again be so certain about the difference between a programming language and a data format.
