ELI5: How a FS JSON DB works?

Imagine you have a toy box where you keep all your favorite toys. You want to find your toys easily and keep them organized. A database is like that toy box, but instead of toys, it holds information, like your favorite games, friends' names, or stories.

Now, let’s think about a special kind of toy box called a JSON database. JSON stands for JavaScript Object Notation, which is just a fancy way to say it keeps things in a neat and tidy format. Think of it like having a box that can hold lots of little boxes, and each little box can have different things inside it.

When you want to put a toy in your toy box, you might say, “This is a red car.” So, you might have a little box that says "car" and inside it, you can have details like "color: red" and "size: small." In a JSON database, it does something very similar. It keeps information in a format that looks like this:

{
  "toy": {
    "name": "car",
    "color": "red",
    "size": "small"
  }
}

When you want to find a toy, you can quickly look for the box that says "car," and then you can see all the details about it. This makes it super easy to find what you want!

Now, let’s say you have a lot of toys. You might have boxes for cars, dolls, and blocks. Each type of toy can have its own little box with its own details. In a JSON database, you can have lots of these little boxes (or "objects") all together, so you can keep track of everything.

The cool part is that you can add, change, or take out toys whenever you want, just like you can add, change, or remove the information in the database. If you get a new blue car, you just add another little box for that!

So, a JSON database is like a super organized toy box that helps keep all your information neat and tidy, making it easy to find and use whenever you need it!
