In JavaScript, there are several data types that are supported. They include:
Primitive Data Types:
String: Represents textual data, e.g., “hello”.
Number: Represents numeric values, e.g., 42.
Boolean: Represents true or false values.
Undefined: Represents a variable that has been declared but not assigned a value.
Null: Represents the intentional absence of any object value.
Symbol (added in ECMAScript 6): Represents unique identifiers.
Non-primitive Data Types (also known as Reference Data Types):
Object: Represents a collection of key-value pairs.
Array: A special type of object used to store ordered collections of data.
Function: A callable object that can be invoked.
Date: Represents a specific moment in time.
RegExp: Represents a regular expression pattern.
These are the primary data types in JavaScript. It’s essential to understand each of them and their respective use cases for effective JavaScript programming.
