# Manipulation Cookies in Java Script

A Cookie is nothing but a small text file that’s stored in your browser. It contains some data such as:\

- A name value pair containing the actual data.
- An expiry date after which it is no longer valid.
- . The domain and path of the server it should be sent to.

We can use Cookie:

- State Maintenance/Persistence across different pages of the site, for Http is a state less protocol which means after sending any web page server forget which page he sent.
- To allow user-side customization of web information, to serve a personalized site.

In this demonstration we learn how to create cookie, delete cookie and read cookie.

##### Creating cookie

```
function createCookie() {            var date = new Date();            var days = 1;            date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));            document.cookie = "ck1" + "Hello Dear" + date.toGMTString();            document.write("Cookie created successfully.");}
```

##### Reading Cookie

```
function readCookie() {            var cookName =  "ck1" + "=";            var ca = document.cookie.split(";");            for (var i = 0; i < ca.length; i++) {                var c = ca[i];                while (c.charAt(0) == ' ')                    c = c.subString(1, c.length);                if (c.indexOf(cookName) == 0)                    document.write(c.subString(cookName.length , c.length);            }}
```
