Hello! In the if clause you have a string ('a > b'), instead if comparing two variables if(a > b). Inside an if clause, if there is only string like if("something") , it will always amount to a truthy value and the else clause wont be executed. For example,

    if("something"){
      alert("This will always amount to true");
    }
    else {
      alert("This wont be executed");
    }

It looks like that is the issue, a>b should not be in quotes because you defined their day type as integers.

i don't clearly get what the problem is here , but i think the condition in the if statement shouldn't be represented as a string like what you have , you might wanna change it this way :

var a = 10;
var b = 20;
var c = 30;
if (a>b) {
alert("a is greater than b");
}else {
alert("a is not greater than b");
}
