JavaScript's Seven Primitive Data Types Explained for Beginners

JavaScript has seven primitive data types that serve as the most fundamental building blocks for handling data in the language. These include String for text, Number for integers and decimals, and BigInt for integers exceeding the safe limit of the standard Number type. Boolean holds only true or false values, while Undefined is automatically assigned to variables that have been declared but not yet initialized. Null is used to explicitly indicate the intentional absence of a value, and Symbol rounds out the seven types. Together, these primitives form the foundation of how data is stored and manipulated in JavaScript programs.
