What is JSON?

  • Share this:

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 based on a subset of the JavaScript programming language, and it is often used to transmit data between a server and a web application or between two systems.

JSON has a simple and intuitive syntax that consists of key-value pairs, arrays, and simple data types such as strings, numbers, and booleans. It is typically used to represent data structures, and it can be easily converted to and from JavaScript objects.

Here is an example of a JSON object that represents a person:

  "name": "John",
  "age": 30,
  "gender": "male",
  "hobbies": ["reading", "music", "travel"]

JSON is widely used in modern web development, as it is a convenient and flexible way to transmit data between different systems and environments. It is supported by almost all modern programming languages and platforms, and it is often used in combination with REST APIs.

It is worth noting that JSON is not the only data interchange format that is commonly used on the web. Other formats, such as XML and CSV, are also used in certain situations. However, JSON has become the de facto standard for data interchange on the web, and it is supported by many tools and libraries.
