var str_small = str.small() ;
var str_bold = str.bold() ;
var str_italic = str.italics() ;
var str_blink = str.blink(); //(does not work in IE)
var str_fixed = str.fixed() ; //Displays a string as teletype text
var str_strike = str.strike() ;
var str_fc = str.fontcolor("Red") ;
var str_fs = str.fontsize(12) ;
var str_lc = str.toLowerCase() ;
var str_uc = str.toUpperCase() ;
var str_sub = str.sub() ;
var str_sup = str.sup() ;
var str_link = str.link("http://www.w3schools.com");

var str_pos = str.indexOf( "o" );

The lastIndexOf() method returns the position of the last occurrence of a specified string value, searching backwards from the specified position in a string.
var str_pos = str.lastIndexOf( "o" );

To use the match() method to search for a specified string value within a string and return the string value if found
