HTML and Hacking in the same title HEE HEE! TIME TO GET MY FREE REDDIT ARROW POINTS! More on reddit.com

Knowing how to use HTML and CSS is akin to knowing how to use a hammer and nails. You're not going to become the architect of a major construction project just because you know how to hammer a nail. JavaScript gets more. . .complicated. If you're referring (as it seems you are) to front-end JavaScript, I'd liken that to knowing how to weld. If you know how to use a hammer and nails, and you know how to weld, you're still not going to be the architect of a major construction project. If you want to do odd jobs, basic contract work, and stuff like that, all you need is a hammer, some nails, and maybe a welder. The metaphor extends pretty handily to software development. If all you know is how to make the front-end of a website look nice, your options are going to be limited to things like building custom themes for a company's WordPress site. They'll tell you what they want, and you'll do your best to make it look nice. If you want to go beyond that, you're going to have to learn more about the whole stack. I'm not saying you have to understand everything. But you're going to have to learn how to tie a front-end to a back-end. You're going to have to know a little bit about what happens when you sent out a fetch. You're going to have to know a little bit about how that data transfer takes place. My best advice is to give it time, and don't stop learning. Free Code Camp is a great resource for moving beyond the front end. I'd also check out this video from The Coding Train, guest starring CJ from The Coding Garden (lots of "code" in those names). I don't expect you to become an expert by watching this one video, but I think CJ does an excellent job of summing up the different parts of a "full-stack" web application. It should put you in the right mindset for starting work on your own projects, or just working on FCC or The Odin Project . You might notice that I'm pointing you at resources for many different technologies. That's because the principles of building web applications are more or less the same across most web frameworks out there. NodeJS, Ruby on Rails, Django, Go, a simple LAMP stack, whatever you end up using, you're going to need to learn how to structure your applications. To fall back to my metaphor from earlier, you'll eventually get to a point where you know not only about hammers, nails, and welding, but also about drafting and planning and architecture. Eventually you'll know more than just how to hammer a nail into a piece of wood, about where that piece of wood goes in a project and, more importantly, why it goes there.[1] I hope that helps. I can point you to other resources, books, tutorials, whatever you need, and this sub will be with you throughout your journey. Never be afraid to ask questions, even if some people respond with stupidly-long walls of text. EDIT: [1]: The reason for that second to last paragraph is just because I didn't want you to get stuck in the "I'm learning " rut that a lot of newbies fall in to. You should never focus on one specific technology stack when you're starting out. You're not going to understand enough about first principles in order to make any meaningful headway into becoming an "expert" in that technology. That isn't to say that you can't pick a stack and stick to it. I just mean that you shouldn't say "I'm learning Ruby on Rails" (as an example), but rather you should think of it as "I'm learning web application development, and I just happen to be using Ruby on Rails". It's a subtle difference, but it's one that took me a long time to understand, and I distinctly remember that being the turning point in my education all those years ago.
