Does Order Of Logic Comparisons Affect Speed In The Same Statement

was wondering if it made sense to optimize the comparison order inside an if() statement if one of the comparison targets is a function call eg:

var a = true,
b = function() {return false;};
if (b() || a) {...}
if (a || b()) {...}

would the second statement run faster because it would theoretically never need to call b() in this situation? can the eval order be relied on? does this depend on the js engine/internal optimizations?
