JavaScript JSON

JSON is a syntax for storing and transporting data.

JSON is used when data is sent from a server to a web page.

What is JSON?

  • JSON stands for JavaScript Object Notation.
  • JSON is a lightweight data interchange format.
  • JSON is language independent *.
  • JSON is “self-describing” and easy to understand.

* The JSON syntax is derived from JavaScript object notation syntax, but the JSON format is text only.

JSON Example

This JSON syntax specifies an employees object: an array of 3 employee records (objects):

{

“employees”:[

  {“firstName”:”John”, “lastName”:”Doe”},

  {“firstName”:”Anna”, “lastName”:”Smith”},

  {“firstName”:”Peter”, “lastName”:”Jones”}

]

}

The JSON Format Evaluates to JavaScript Objects

The JSON format is similar to the code for creating JavaScript objects.

Due to this similarity, a JavaScript program can be used to convert JSON data into native JavaScript objects.

JSON Syntax Rules

  • Data is in name/value pairs.
  • Data is separated by commas.
  • Curly braces hold objects.
  • Square brackets hold arrays.
