Do you prefer “if (var)” or “if (var != 0)”? [closed]

Answer 1

I go with readability like most people, I like being able to scan my code and read it without having to think too much, it goes hand in hand though with well named variable names. If your variable names make it sound like it should be a plain if(isPurchasable) then I go with it however it referes to a number or date or similar fasion I use if(stock > 0).

Having to write a comment for an if statement too me is a horrible idea if the expression is so simple, an if statement like below though I can see why comments should be used.

if(isPurchasable && stock > 0 && credit >= cost && !reserved) { 
     // Checks to see if customer can purchase product.
}
