The possibility to interact with the cookies using Java Script code running within the scope of the web browser sets the foundation for many new innovative SDKs. The Facebook Java Script SDK is one of them.
Most web developers are not aware of the possibility to interact with our cookies using code written in Java Script executed within the web browser.

The Java Script Programming course that I deliver at www.xperato.com  covers this technical possibility.
The following video clips explain how we can use Java Script to create a cookie and to read the data of an already existing one.
