JSON is a text format that consists of key-value pairs. The keys are strings and the values can be any valid JSON data type, including numbers, booleans, null, arrays, and other objects. Here is an example of a simple JSON object:
"city": "New York"
In this example, "name", "age", and "city" are the keys, and "John", 30, and "New York" are the corresponding values.
JSON is often used in web APIs to transmit data between a server and a client. It is also used as a configuration file format in many applications. JSON is a popular alternative to XML, which is another format commonly used for data interchange.
JSON data is represented as key-value pairs, where the keys are strings and the values can be strings, numbers, objects, arrays, or a boolean or null value. For example, a JSON object might look like this:
"name": "John Smith",
"name": "Jane Doe",
"name": "Bob Johnson",
This represents an object with four key-value pairs. The
friends key has an array value, which contains two objects with their own key-value pairs.
