What is JSON?

JSON stands for JavaScript Object Notation. It is a way to store and exchange information (data) that is easy for both humans and computers to read. Think of it as a language that makes it easier to share data between different programs or websites.

Why Do We Use JSON?

We use JSON because:

• It's lightweight, which means it doesn’t take up much space.
• It's easy to understand and write.
• Many programming languages support it, making it very versatile.

How Does JSON Look?

JSON is structured with key-value pairs. This means that each piece of data has a key (like a name) and a value (the actual information). Here’s a simple example:

{
  "name": "Alice",
  "age": 12,
  "favoriteColor": "blue"
}

In this example:

• "name" is a key, and "Alice" is its value.
• "age" is a key, and "12" is its value.
• "favoriteColor" is a key, and "blue" is its value.

JSON Syntax Rules

Here are some important rules to keep in mind when writing JSON:

• Data is organized in objects and arrays.
• Objects are enclosed in curly braces { }.
• Arrays are enclosed in square brackets [ ].
• Key names must be wrapped in double quotes ("").

Example of a JSON Object and Array

Here’s a more complex example that includes an array:

{
  "name": "Alice",
  "age": 12,
  "hobbies": ["reading", "swimming", "gaming"]
}

In this example, "hobbies" is an array that contains multiple values.

Where Do We See JSON?

JSON is everywhere! It’s commonly used in web applications, APIs (which allow different software to talk to each other), and configuration files.

Conclusion

JSON is a simple and effective way to handle data. It makes sharing and storing information easy and is widely used in programming. Now that you understand the basics of JSON, you can start exploring how it works in your own projects!
