String In Java Script

String type deals with a single character or a series of characters enclosed with single quotes or double quotes respectively.
 
Initializing string type variables
 
var sect = ‘a’
var is JavaScript keyword, sect is a variable name, a is value assigned to sect variable, variable sect is of string type because the value assigned to sect is of string type.
 
var country=”India”
var is JavaScript keyword, country is a variable name, India is value assigned to country variable, variable country is of string type because the value assigned to country is of string type.
 
In the example given below we have used keyword document.write (message ) which is used to print the message or variable value given with it.
 
Example 1
 
<html>

<head>

</head>

<body>

<script type=”text/JavaScript”>

var sect=’a’

document.write(“Section is  : “+sect);

</script >

</body>

</html>

 
 
Understanding the program
 
<script > tag is the start of a  JavaScript  program, var is to declare a variable of name sect and  ‘a’  is the value assigned to the variable sect. document.write is used to print the given message and/or value of a given variable. We have used + sign here which is used to concatenate the message ( Section is : ) and the value of variable sect (a).
