In AngularJs, we need to use angular-cookies.js to set, get and clear the cookies.

We need to include $cookies in your controller and it have to Get, Set and Clear method to get, set and clear cookies respectively.

Angular has inbuilt directives named as ngCookies.

Writing Cookies:
The WriteCookie function of the controller gets called When the Write Cookie Button is clicked. The WriteCookie function saves the input box value as cookies, using the $cookieStore service of the ngCookies module.

The $cookieStore put function has two parameters:
- Name (Key)
- Value
Syntax:
```
$scope.SetCookies = function () {
    $cookies.put("username", $scope.username);
};
```
Reading Cookies:
The ReadCookie function of the controller gets called when the Read Cookie Button is clicked. The ReadCookie function fetches the value of the Cookie using the $cookieStore service of the ngCookies module.

The $cookieStore get function has one parameters:
- Name (Key)
Syntax:
```
$scope.GetCookies = function () {
    $window.alert($cookies.get('username'));
};
```
Removing Cookies:
The RemoveCookie function of the controller gets called when the Remove Cookie Button is clicked. The RemoveCookie function removes the Cookie using the $cookieStore service of the ngCookies module.

The $cookieStore remove function has one parameters:
- Name (Key)
Syntax:
```
$scope.ClearCookies = function () {
    $cookies.remove('username');
};
```
