JSON stands for JavaScript Object Notation. It is a lightweight data interchange format that is easy to read and write for humans. JSON is often used to transmit data between a server and a web application, as an alternative to XML.
Data Type
JSON has several data types that can be used to represent different kinds of values:
1. String
A string is a sequence of characters, enclosed in double quotes. It can contain any Unicode character, including escape sequences.
2. Number
A number can be an integer or a floating-point value. JSON does not differentiate between different number types like integers, floats, or doubles.
3. Boolean
A boolean value can be either true or false. It represents the logical values of true and false.
4. Array
An array is an ordered collection of values, enclosed in square brackets []. Each value within the array can be of any JSON data type, including another array or object.
5. Object
An object is an unordered collection of key-value pairs, enclosed in curly braces {}. Each key within the object must be unique, and the value can be any JSON data type.
6. Null
The null value represents the absence of a value or the intentional assignment of no value.
Example:
Here’s an example of a simple JSON object:
{
"name": "John",
"age": 30,
"isStudent": false,
"hobbies": ["reading", "coding", "gaming"],
"address": {
"street": "123 Main St",
"city": "New York",
"country": "USA"
},
"favoriteColor": null
}
In this example, the JSON object contains a string (name), a number (age), a boolean (isStudent), an array (hobbies), an object (address), and a null value (favoriteColor).
Conclusion
JSON is a versatile data type that can represent various kinds of values. It provides a simple and readable way to structure and exchange data between different systems. Understanding the different data types in JSON is crucial for working with JSON data effectively.
