Diabetes 'Cure': Diet & Exercise Work for Some. People with Type 2 diabetes can reverse their condition with diet and exercise, although remission is not very common, according to a new study from the Centers for Disease Control and Prevention.

JSON is a format for storing and transporting data.

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

* The JSON syntax is derived from JavaScript object notation syntax, but the JSON format is text only. Code for reading and generating JSON data can be written in any programming language.

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

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

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

JSON data is written as name/value pairs, just like JavaScript object properties.

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

JSON objects are written inside curly braces.

Just like in JavaScript, objects can contain multiple name/value pairs:

JSON arrays are written inside square brackets.

Just like in JavaScript, an array can contain objects:

In the example above, the object "employees" is an array. It contains three objects.

Each object is a record of a person (with a first name and a last name).

A common use of JSON is to read data from a web server, and display the data in a web page.

For simplicity, this can be demonstrated using a string as input.

First, create a JavaScript string containing JSON syntax:

Then, use the JavaScript built-in function JSON.parse() to convert the string into a JavaScript object:

Finally, use the new JavaScript object in your page:
