JavaScript Data Types

JavaScript Data Types

All Variables have a data type that defines what type of data is being stored in a variable. There are two types of data types in JavaScript namely Primitive data types and Non-primitive data types.

JavaScript Primitive Data Type

Primitive data types: those not defined in terms of other data types. In other words we can say that in-built data type. Most programming languages provide a set of primitive data types.

JavaScript primitive data types are as follows:

• string 
• number
• bigint 
• Boolean 
• undefined  
• null
• symbol

JavaScript non- Primitive Data Type

Primitive data types: those defined in terms of other data types.  In other words we can say that derived data type.

JavaScript non-primitive data types are as follows:

• Object 
• Array
