JSON
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is often used for exchanging data between a web server and a web application, as well as between different programming languages.
JSON is commonly used in web development to transfer data between a web server and a web application. For example, when a web application makes a request to a web server, the server might respond with a JSON object or array containing the requested data.
Some technologies have been built on top of JSON like JWT, JSONPatch or JSON Schema.
JSON Syntax
JSON is built on two structures: objects and arrays. An object is an unordered set of key/value pairs, while an array is an ordered collection of values.
Here is an example of a JSON object:
{
"name": "John",
"age": 30,
"city": "New York"
}
In this example, "name", "age", and "city" are keys, and "John", 30, and "New York" are values. The keys and values are separated by a colon, and each key/value pair is separated by a comma. The entire object is enclosed in curly braces.
Here is an example of a JSON array:
[
"apple",
"banana",
"orange"
]
In this example, "apple", "banana", and "orange" are values. The values are separated by commas, and the entire array is enclosed in square brackets.
