JSON Tutorial
JSON: JavaScript Object Notation.
JSON is syntax for storing and exchanging text information. Much like XML.
JSON is smaller than XML, and faster and easier to parse.
JSON Example
{
"employees": [
{ "firstName":"John" , "lastName":"Doe" },
{ "firstName":"Anna" , "lastName":"Smith" },
{ "firstName":"Peter" , "lastName":"Jones" }
]
}
"employees": [
{ "firstName":"John" , "lastName":"Doe" },
{ "firstName":"Anna" , "lastName":"Smith" },
{ "firstName":"Peter" , "lastName":"Jones" }
]
}
The employees object is an array of 3 employee records (objects).
What is JSON?
- JSON stands for JavaScript Object Notation
- JSON is lightweight text-data interchange format
- JSON is language independent *
- JSON is "self-describing" and easy to understand
| * | JSON uses JavaScript syntax for describing data objects, but JSON is still language and platform independent. JSON parsers and JSON libraries exists for many different programming languages. |
JSON - Evaluates to JavaScript Objects
The JSON text format is syntactically identical to the code for creating JavaScript objects.
Because of this similarity, instead of using a parser, a JavaScript program can use the built-in eval() function and execute JSON data to produce native JavaScript objects.
