javascript - Error: Uncaught SyntaxError: Unexpected identifier -

i'm making simple blackjack game in javascript, when try run it, gives me error. specifically, chrome tells me error on line:

if y <= 17 

here's code:

var x = null; var y = null; var numsdeal = new array(); (i=0;i<2;i++){     ndeal = math.floor(math.random()*(11-1)+1)+1;     numsdeal[i] = ndeal;     y = numsdeal[0]+numsdeal[1]; }    var nums = new array(); (i=0;i<2;i++){     n = math.floor(math.random()*(11-1)+1)+1;     nums[i] = n;     x = nums[0]+nums[1]; }  function hit(){ hitc = math.floor(math.random()*(11-1)+1)+1; x = x + hitc;     if y <= 17         hitd = math.floor(math.random()*(11-1)+1)+1;         y = y + hitd         y.tostring();         document.getelementbyid("demo2").innerhtml = y; x.tostring(); document.getelementbyid("demo").innerhtml = x; }  x.tostring();  document.getelementbyid("demo").innerhtml = x; 

as can see, y declared. can me? i'm sure i'm being stupid.

by way, have searched solutions, both can't understand them i'm beginner, , don't think they're same problem. hope proven wrong.

you should listen browser...

if ( y <= 17 ) {     // ... }
