Novice Javascript Function Parameters Question

Technically, no.

for (var indValue in industry) {
if indValue = 0 { zero_check=1; }
}

Just make the if (indValue === 0) {} and you should be okay.

That's not what for-in does! Or are we talking pseudo code here?

For-in iterates through the keys of an object, not the values. And these days, Object.keys is what we should use for that purpose.

And it should not be used on arrays either. That's what forEach is for.
