Hey everyone! I'm new to programming and trying to wrap my head around how real projects, especially JavaScript or React ones, are structured. When I dive into these projects, I often see folders like `src`, `public`, `dist`, and sometimes `build` or `assets`. I'm curious about what each of these folders typically contains:
- What's usually found in `src`?
- What does the `public` folder hold?
- What's the purpose of `dist` or `build`?
- Are these folders mandatory, or do they depend on what framework you're using?
- Is there a general structure that most projects adhere to?

Here's a breakdown:
- **src**: This is where you'll find the code you actually write. Think of it as the brain of your app that you can edit.
- **public**: This folder is for static files—things like your main HTML file, images, or any icons that need to be directly served by the browser.
- **dist/build**: This is where the magic happens. After you run the build command, the compiled and optimized files go here. This is what you deploy to production.
It's not set in stone; these terms are conventions adopted by various tools like Webpack or Create React App to keep everything neat and tidy.
In most projects, `src` is where all your source code lives—the actual code that you write, including things like React components, JavaScript files, and CSS. It's essentially the core of your project where you do your developing.
The `public` folder usually contains static files that the browser can access directly, such as `index.html`, images, and icons. Basically, stuff that you want to serve as-is.
And then you have `dist` or `build`, which is generated output that your project produces once it’s built. This directory contains the final optimized files ready for deployment; you don’t write code here.
While these folders aren't strictly essential, they are commonly used patterns in many frameworks to keep things organized. The actual structure can vary between different languages or frameworks though.
These folder structures are pretty standard conventions. Just to summarize:
- **src** = the actual source code that you write.
- **public** = static assets that the client can access directly like HTML, JS, and images.
- **dist** or **build** = output files that are generated after bundling your code for production.
They're helpful for organizing projects, but you can technically structure your projects however you want. If you want to really grasp this, try creating a small project and see how the folders are structured after you go through the build process!
