Question

I have an object property that may or may not contain a number and that number may or may not be equal to 0. For the moment, I have this:

var TheVar = parseInt(SomeObject.SomeVar, 10);

if (!TheVar > 0) {
   TheVar = "-";
}

I want TheVar to be either a positive number or "-". I’m just wondering if my conditional statement is going to cover every case?

Thanks for your suggestions.

Answer 1

No. You are missing parentheses.

if( !(TheVar > 0))

NaN > 0 returns false, so the if condition will go through.
