javascript - Palindrome program - unexpected identifier error -


i trying write js program print largest palindrome between 1 , 1000 (929). getting uncaught syntaxerror: unexpected identifier on line 4 of code:

    var num = 1;      (var i=0;i<=1000;i++) {       if == reverse(i) && isprime(i)           num = i;           console.log(num);     }     document.write(num);      function reverse(s) {         var o = '';         (var = s.length - 1; >= 0; i--)             o += s[i];       return o;     }      function isprime(number) {         var start = 2;         while (start <= math.sqrt(number)) {             if (number % start++ < 1) return false;         }         return number<=1 ? false : true;     }

what uncaught syntaxerror: unexpected identifier? , how fix bug?

your if statement missing parenthesis () , block identifiers {}.

the syntax javascript if statement follows:

if (condition) {      //  } else {      // else }

so, change if code above , should good!
