Primitive Types









JavaScript has five primitive types: Undefined, Null, Boolean, Number, and String.

Each of the primitive types defines a range of values as well as literal representations of that type.

To determine if a value is in the range of values for a particular type, JavaScript provides the typeof operator.

This operator can be used to determine if a value represents a primitive type.
