Hi, I had planned to create java script tutorials for students and readers of my blog. here I will discuss very important points regarding java script. I will keep updating this post so readers are advised to visit it frequently. I would also like to share some important javascripts as below. 1. javascript to find first 10 prime numbers. <html><head> <title>first 10 prime numbers </title> </head> <body> <script type="text/javascript"> var count=10,i=0,j=0,k=2; document.write("<br/><h2>first 10 prime numbers.</h2>"); for(i=0;i<count;k++) { var isprime = true; for(j=2;j<=k-1;j++) { if(k%j == 0){ isprime = false; break; } } if(isprime == true){ document.write("<br/> prime no : "+k); i++; } } </script> </body> </html> output of the script is as below.
