#3 JavaScript DataType

In JavaScript, data types categorize the kind of values variables can hold, each serving a specific purpose. Primitive data types include strings (text), numbers (integers and floats), booleans (true/false), undefined (uninitialized values), null (intentional absence), and symbols (unique identifiers). Objects, the most versatile data type, group key-value pairs, allowing complex data structures. Special types, like functions (executable code), arrays (ordered lists), and dates (representing time), enhance functionality. JavaScript's loose typing permits variables to change types dynamically, providing flexibility but demanding careful consideration. Understanding these data types is fundamental for effective programming and manipulation of data within the language.
