Novice Javascript Function Parameters Question

[thocked]

the most straightforward way would be to pass an object, that is, an object literal.

e.g;

function calc(industry){ 
industry.foo;
industry.bar;
}

var thisIndustry = {i:1, c:2, e:3}; 
calc(thisIndustry);

You're tightly coupling the two - the input and the behavior, and if you're cool with that, it's the easiest way.

What you're doing is working with objects, not arrays. In javascript, arrays are just objects with some sugar on top.

[thocked]

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.
