JSON

Définition

JSON stands for JavaScript Object Notation, and is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate.

In simpler terms, JSON is a way to store and transmit data in a standardized format that can be easily understood and processed by different programming languages and systems.

Here is an example of JSON data:

{ "name": "John", "age": 30, "city": "New York" }

This JSON data represents an object with three properties: "name", "age", and "city". Each property is represented by a key-value pair, with the key on the left side of the colon and the value on the right side.

In this example, the "name" property has a value of "John", the "age" property has a value of 30, and the "city" property has a value of "New York". Note that string values are enclosed in double quotes.

JSON can be used to represent more complex data structures, such as arrays and nested objects. Here is an example of JSON data that includes an array:

{ "name": "Mary", "age": 25, "cities": ["London", "Paris", "Berlin"] }

In this example, the "cities" property is an array that contains three string values: "London", "Paris", and "Berlin".

Overall, JSON is a flexible and widely used format for storing and transmitting data in web applications, APIs, and other software systems. Its simple syntax and broad support across programming languages and platforms make it a popular choice for data interchange.
