With JavaScript, you can easily access/ read cookies with the “document.cookie” property. Reading a cookie is just as simple as writing one because of the value of the document.cookie object is the cookie.
The document.cookie string will keep a list of name=value pairs separated by semicolons, where the name is the name of a cookie and value is its string value.
Example
