What is JSON?

"JSON" means JavaScript Object Notation.

JSON is a lightweight data exchange format

JSON is language independent *

JSON is "self-describing" and easy to understand

* the syntax of JSON is from the syntax of JavaScript object symbols, but the JSON format is plain text. The code that reads and generates JSON data can be written in any programming language.

JSON instance

The JSON syntax defines an employee object: an array (object) containing three employee records:

JSON instance

{

"employees": [

{"firstName": "Bill", "lastName": "Gates"}

{"firstName": "Steve", "lastName": "Jobs"}

{"firstName": "Alan", "lastName": "Turing"}

]

}

JSON format is evaluated as a JavaScript object

The JSON format is syntactically the same as the code that creates the JavaScript object.

Because of this similarity, JavaScript programs can easily convert JSON data into native JavaScript objects.

JSON grammar rules

The data is a name / value pair

Data is separated by commas

Curly braces save objects

Square brackets save array

JSON data-name and value

JSON data is written as name / value pairs, similar to JavaScript object properties.

The name / value pair consists of the field name (in double quotes), followed by a colon, followed by a value:

"firstName": "Bill"

The JSON name requires double quotation marks. The JavaScript name is not required.
