data types in javascript

- by Mcs June 30, 2025
JavaScript data types categorize the different kinds of values that can be stored and manipulated within the language. These are broadly divided into two categories: primitive and non-primitive.
JavaScript has two main categories of data types:
1. Primitive Data Types
These hold a single value.
2. Non-Primitive (Reference) Data Types
These hold collections of values or more complex data.
