JS 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, let or const here to specify the data type. It can hold any type of values such as numbers, strings etc. For example:

Primitive data type

Data type	Description
String	represents sequence of characters e.g. "hello"
Number	represents numeric values e.g. 100
Boolean	represents boolean value either false or true
Undefined	represents undefined value
Null	represents null i.e. no value at all

Non Primitive data type

Data type	Description
Object	represents instance through which we can access members
Array	represents group of data having similar data types
Regex	regular expression

Now that you know data types in javascript, let's learn operators, types of operators
