JSON (JavaScript Object Notation) is a widely used data-interchange format for transmitting data in web services and applications.

JSON Key Features and Uses:
JSON is based on a subset of JavaScript syntax and is easy for humans and machines to read and write.
JSON is designed to use universal data structures. Virtually all modern programming languages support them in one form or another.

Human-readable: JSON is designed to be easily understood by humans, making it very suitable for debugging and development tasks.
Machine-readable: Its structured nature allows computers to easily parse and process JSON data.
Language-independent: While based on JavaScript syntax, JSON is not tied to any specific programming language and can be used across various platforms.
Commonly used in applications: JSON is frequently used for sending and receiving data between servers and web applications or mobile devices, for example, in APIs and RESTful services.
JSON is a lightweight data-interchange format and it is easy for machines to parse.
General : JSON structure is very flexible and can be adapted to describe many types of objects, persons, companies, purchases or diffent kinds of information.

JSON can represent data with several types, including:
Strings: Represented as text enclosed in double quotes.
Numbers: Integers and decimals.
Booleans: true or false.
Null: Represents the absence of a value.
Arrays: Ordered lists of values, enclosed in square brackets.
Objects: Collections of key-value pairs, enclosed in curly braces.

JSON works based on javascript notation and can represent data included in a general structure.
JSON Structure:
Objects: Represented as collections of key-value pairs, where keys are strings in double quotes and values can be any JSON data type.
Arrays: Represented as ordered lists of values, where values can be any JSON data type.

Show me one example in JSON:
Here is one example of code in json format :

{
  "name": "John Doe",
  "age": 30,
  "city": "New York",
  "isStudent": false,
  "grades": [85, 92, 78],
  "address": {
    "street": "123 Main St",
    "city": "Anytown",
    "zip": "12345"
  }
}

You can use the JSON format for API development and data interchange.
Why choose JSON as the standard for your project?
JavaScript Object Notation (JSON) is very general format that can represent many data in a structured syntax, easy to read by humans and machines.
It is commonly used for transmitting data in web or mobile applications
Data can be used and read from any programming language.
Can be used to send some data from the server to the client, and display it on a web page, or vice versa.
