JSON
#refactor
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.
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.
