# No type cast (JS is loosely type language)
# No need to specify types of variable. (Dynamic Script Language)
There required using var to specify data types, it can hold any type of variables like number, String.
Var height= 34; // number
Var volume=35; // number
Var name="arie" // string
Data Types are categorized into two types:
2) Non primitive
1) Primitive Datatypes:
Immutable datatypes are referred as primitive datatypes because once these data values gets creates there is no another method to modify it.
A Boolean data type characterizes only two values i.e. true, or false.
var booleon7 = true;
var booleon8 = false;
Suppose number1 = 65;
Suppose number2 = 93.00;
This type of datatype contains one undefined value i.e. a value is not assigned to a variable
Var h="welcome in codingtag";
A variable found to have a null value i.e. an empty variable.
var z = null;
var f = 'codingtag!';
var g = "codingtag!";
2) Non-primitive Datatypes
