JavaScript variable are the basic building blocks the javascript programming. A variable is a memory location which assigns a value to it whenever your declare a variable.
javascript variables are like containers in the memory of the computer,
when we declare a variable it select a random memory location and give it the name that the user provides, and when a value is assigned to that variable , that value is stored to that memory location.
So lets see how the variables are declared.
A variable in javascript is created using the keyword 'var'.

<html>
<head>
<title>codeMystery</title>
<center><h1>JavaScript Variables, types and operators</h1></center>
<script type="text/javascript" >
var _newVar2, newVar3 = 45, z;
_newVar2 = 45.78;
//alert(_newVar2);
document.write(_newVar2);
alert(typeof(_newVar2));
