In JavaScript, a data type defines the type of value that can be stored and manipulated in a variable. It determines the behavior and operations that can be performed on that value. JavaScript has several built-in data types, including:

1)  Primitive Data Types:
·     Number: Represents numeric values, both integers and floating-point numbers.
·     String: Represents a sequence of characters.
·     Boolean: Represents a logical value, either true or false.
·     Null: Represents the intentional absence of any object value.
·     Undefined: Represents an uninitialized or undefined value.
·     Symbol: Represents a unique identifier.

2)  Complex Data Types:
·     Object: Represents a collection of key-value pairs, where values can be of any data type, including other objects, arrays, and functions.
·     Array: Represents an ordered list of values, where each value can be of any data type.
·     Function: Represents a reusable block of code that performs a specific task.

It’s important to note that JavaScript is a dynamically typed language, which means that variables are not bound to a specific data type. The data type is inferred from the value assigned to the variable.
