what is true inside if condition

In line 131 there is if statement 

function requiredFilledIn(){
       if(true)  $submit.attr("disabled",disabled);
       else $submit.removeAttr("disabled");
}

I want to ask what is if(true) condition checks here ? I could not get true concept in this line here?

In JavaScript, if statements are executed if the parameter to the if statement returns true. So, for example, 5 > 3 would return true, 1 === 1 would return true, and 8 !== 4 would also return true. In this case, you're just passing the value true into the if statement. You're essentially just being very direct and saying "Yeah, the value's true. Just run the code". This causes the if statement to run every time (thereby making the if statement altogether unnecessary), but you'll never do that in an actual scenario.
