**JSON ( JavaScript Object Notation )** is a lightweight text-based language. The data can only be text while it is being exchanged between a browser and a server. Any JavaScript object can be converted into a JSON text.

# Data structures in JSON
JSON supports these two data structures:

A JSON can store several types of values, listed in the table below:

|  Values   |  Description   |
| --- | --- |
|  String   | In JSON, strings are enclosed in double quotes and there are many special characters like *b (backspace)*, *t (tab)*, etc.     |
|  Number   |  JSON supports different number types like integer, fraction and exponential.   |
|  Boolean   |  In JSON, `true` or `false` value can also be assigned.    |
|  Null   |  In JSON, an empty value can be assigned.   |

### Collection of key-value pairs

Here, key-value pairs are always placed between curly brackets ({ }). If there is more than one key-value pair, they are separated by commas. 

### An ordered  list of values

Here, values are enclosed in square brackets ([ ])and each value is separated by a comma..

What are JSON structures?

JSON is a lightweight text format supporting strings, numbers, booleans, null, key-value pairs, and arrays.

Values	Description
String	In JSON, strings are enclosed in double quotes and there are many special characters like b (backspace), t (tab), etc.
Number	JSON supports different number types like integer, fraction and exponential.
Boolean	In JSON, `true` or `false` value can also be assigned.
