Expert's answer
You can generate required patterns in such way: -Pattern * ** *** **** JavaScript: document.write('Pattern#1</br>'); varcount=10;//maximum number of * symbol varpattern=''; for(var i=1;i<=count;i++) { document.write((pattern+='*')+'</br>');//changepattern and write it to document } -Pattern ***** *** * * *** ***** Javascript: document.write('Pattern#2</br>'); varpattern='*****'; varaddIt=''; varaddItSymb=' ';//symbol to add /* ***** *** * */ while((2*addIt.length)<pattern.length) { document.write(addIt+pattern.substring(0,pattern.length-2*addIt.length)+addIt+'</br>'); addIt+=addItSymb; } /* * *** ***** */ while(addIt.length!=0) { addIt=addIt.substring(0,addIt.length-1); document.write(addIt+pattern.substring(0,pattern.length-2*addIt.length)+addIt+'</br>'); } To view results you can use such HTML document <html> <head> <scripttype="text/javascript"> <!--INSERT JAVASCRIPT HERE --> </script> </head> <body> </body> </html>
