# Delete a cookie using javascript

JavaScript can create, read, and delete cookies with the document.cookie property.

## Syntax

document.cookie = "key1 = value1; key2 = value2; expires = date";


Where:
expires: is an optional attribute which specify the date of cookie expiration.

## Example

document.cookie = "username=jai;


We don’t have to specify a cookie value when we want to delete a cookie. We have to set the expires parameter to a passed date.

## Delete a cookie using javascript
