Let's have a quick look at the basic syntax of JSON. JSON syntax is basically considered as a subset of JavaScript syntax; it includes the following −

  • Data is represented in name/value pairs.

  • Curly braces hold objects and each name is followed by ':'(colon), the name/value pairs are separated by , (comma).

  • Square brackets hold arrays and values are separated by ,(comma).

Below is a simple example −

{
   "book": [

      {
         "id": "01",
         "language": "Java",
         "edition": "third",
         "author": "Herbert Schildt"
      },

      {
         "id": "07",
         "language": "C++",
         "edition": "second",
         "author": "E.Balagurusamy"
      }

   ]
}

JSON supports the following two data structures −

  • Collection of name/value pairs − This Data Structure is supported by different programming languages.

  • Ordered list of values − It includes array, list, vector or sequence etc.
