"Maybe that's what we should rant against."
That hits a nerve with me, because I think that's what happened to me. I raised my hand at work one day and said I'd like to help design and develop a new SPA, having only done one static site before. There was no one else I could learn from, so I went to a framework because they wanted the project (of unknown complexity) done in a certain amount of time. I needed a shortcut. Now, being that I didn't know JS, build systems, etc etc either, it was hard at times when I was stuck to know whether I needed to search SO or the framework docs, but the benefit as a new developer was the conventions and organization that the framework brought. Since that time 5 years ago, I've learned a LOT more about JS, and frameworks are somewhat easier to use. I think they are valuable when you have SPAs to build and low-maturity devs. And my opinion is that if you have a project of any complexity, and more than one developer, you will create your own conventions and your own system and unless everyone really knows what they're doing, it will be a Frankenstein framework anyway, so why not use a a framework like Angular, React, or Vue that already has established conventions and decent documentation, and then senior devs can help juniors identify where vanilla JS is the better option.
"So let's say we have a beginner wanting to learn webdev and they have an idea about the thing they want to make. Can they make it in vanilla html/css/js? Of course they can. If they know those languages inside and out. Which they don't. Because they're beginners."
That's kinda the point though. If you don't understand the basics enough to use the holy trifecta to make something. YOU NEED TO LEARN THEM!!! Why? Becasue all those frameworks and libraries use them. And adding another layer of abstraction on top of something you don't understand well is very difficult. I graduated from a coding bootcamp and knew React pretty darn well by the time I graduated. And now I work for a company building stuff in Angular 2+ all day every day. I find the thing that helps me grow the most as a dev is building complicated things with nothing but the basics. Learning to do that helps so much in equiping you to jump from framework to framework.
