Javascript Data Types

JavaScript provides different data types to hold different types of values. There are two types of data types in JavaScript.

1. Primitive data type
2. Non-primitive (reference) data type

JavaScript is a dynamic type language, means you don't need to specify type of the variable because it is dynamically used by JavaScript engine. You need to use var here to specify the data type. It can hold any type of values such as numbers, strings etc. For example:

There are five types of primitive data types in JavaScript. They are as follows:

JavaScript non-primitive data types

The non-primitive data types are as follows:

We will have great discussion on each data type later.
