JavaScript Object Notation

JavaScript Object Notation (JSON) is a way of creating an object in JavaScript with its properties initialized to specified values. A comma-separated list of key:value pairs is enclosed in braces, as shown in the following JSON example.

var person = {name:"Harry", age:17};

An object is created with properties name and age, which are initialized to "Harry" and 17, respectively. It is equivalent to the following JavaScript code.

var person = new Object();
person.name = "Harry";
person.age = 17;

JSON notation helps in making JavaScript code simpler and easier to read.
