Can you list the data types in JavaScript that are considered primitive types?

In JavaScript, primitive types are considered to be:

• string — a string, for example, "hello"
• number — a number, for example, 42 or 3.14
• bigint — integers of arbitrary length, for example, 9007199254740991n
• boolean — a logical type: true or false
• undefined — the value of a variable that has not been initialized
• null — a special value representing "no value"
• symbol — a unique and immutable identifier

Primitives are stored directly in the stack and are passed by value, unlike objects, which are passed by reference.
