How can we use a string in javascript?
How to use the special characters '(quote), "(double quote), \(backslash), newline, tab in javascript string variable?

Explanation

String- E.g: "sdfesdfe"
For a variable to be a string type, the value assigned should be given in quotes.
A number given within quotes will be considered only as a string and not as an integer.
i.e if

var a = "2";
var b = "2";

then a+b will give "22" and not 4.

Special Character's: To use the special characters like tab, newline, back space, double quotes, etc.. in string variable the following format should be used

Character	Code to be used
Single Quote	\'
Double Quote	\"
Backslash	\\
Horizontal Tab	\t
New Line	\n
Back Space	\b
Carriage Return	\r

Example Code:
<script language="javascript">
var as = "this is \"a\" \'test\'";
document.write(as);
</script>

Result:
this is "a" 'test'
