Of course, but OOP is typically about putting methods on classes, inheritance of behaviour etc.
JS Objects aren’t typically used that way, they tend to be used as pure data containers. At least, that’s how we mostly use them.
Occasionally, we’ll use objects to simplify passing multiple arguments including arrow functions, but I’d say that doesn’t really count unless the arrow function mutates the object it’s a part of.
I’ve been on that platform since 2014. It’s a mix of an anime tracker and a Facebook-like social media site. Used to be called Hummingbird.
It’s alright, if a bit dated.
