Exploring Primitive Data Types

Summary

The video explains JavaScript data types, highlighting their role in handling and processing data. It categorizes types into primitive and object. Primitive types covered include number (e.g., for values like 8), string (e.g., for text like a name), boolean (true or false), null, and undefined. The presenter focuses on these basics, noting that more advanced topics will be addressed later.
