A No-Nonsense Intro to JSON

Published: · Updated:

This JSON thing is everywhere. Why? Because it’s the simplest way to pass data around the web. If you work with code, at some point you’re going to need to understand JSON. So, let’s dive in without getting hung up on jargon.

What is JSON?

Alright, forget the acronyms. It’s really just text, but it’s organized in a way that both humans and computers get. Think of it like a super lightweight way to write an outline.

How JSON Works

It has just two parts:

  1. Names and Values: Kinda like a list of ingredients, you’ve got the name of the thing (“flour”), then a colon (":"), then how much (“2 cups”).

  2. Groups: Sometimes you need to group things together. Picture a recipe within a recipe. That’s where curly brackets {} and square brackets [] come in - they keep things tidy.

Why JSON is King

Where You’ll See JSON

Okay, But How Do I USE It?

Most languages have ways to turn JSON into code you can work with, and back again. Don’t worry about that too much right now. The big idea is to understand the structure.

Security Note

Just be careful about blindly trusting JSON data from somewhere else. Bad guys can try to sneak malicious code in there. Always check your inputs.

The Bottom Line

JSON isn’t some mind-blowing technology. It’s a tool.

It solved a problem (passing data around) simply, and that’s why it took over.
