Data Types

JavaScript Data Types

In JavaScript Data Types, the term datatype mainly refer to the different types of values with which a program can work.

JavaScript Variables can work with three primitive data types, such as numbers, strings, boolean and further non-primitive data types are objects, date, arrays.

For executing a program, it is important to know a data type of variables because without data type it is quite impossible for a computer to produce the output of a program.

Unlike any other programming language, JavaScript does not define different type of numbers, like integers, short, long, floating-point, etc.

Primitive Data Types

For example,

var x = 10;                       //number             
var str = “TutorialLink” ;        //string      
var name = [ “Nitin”, ”Pandit” ];  //array   

Here, the variable x is a number data type as it assigns a value of 10. The variable str is a string data type as it assigns a value in a sequence of characters as “TutorialsLink”. The variable name defined as an array data type.
