What is a cookie script?

A cookie script is a piece of code inserted into a website’s programming that manages how cookies, small pieces of data, are stored and utilized when users visit the site. Cookie scripts are mostly written in JavaScript and executed when a webpage loads. They can perform various functions such as storing login credentials, tracking page visits and clicks, remembering items in a shopping cart, and delivering targeted ads.

While cookies can enhance user experience, they also raise privacy issues due to tracking across websites. Users have some control via browser settings to delete or restrict cookies. However many sites nudge users to enable cookies for full functionality. Websites should obtain informed cookie consent from visitors before loading the cookie scripts on the user’s device.
