For Loops

[Gregc.]

Hi

I am not sure you guys can help me, but here it goes. am having
trouble understanding for loops. If I have a loop that says:


var coffee = new Array();
coffee ["mixedblend"] = 5.50;
for (c in coffee)

{code goes here}

That for saying while there is a c in coffee, then conduct the code.
Is that a correct interpretation?

No.

Consider and try the following

var coffee = new Array();
coffee ["mixedblend"] = 5.50;
coffee ["grots"] = 1.50;
for (c in coffee) alert (c + " costs " + coffee[c])

IMHO, it is generally better to use Array only for numeric indices, and
the above could start var coffee = {} // empty Object.

The ordering apparent in coffee by for (c in coffee) is undefined.

You should use var c; and, as that is essentially an indexing operation,
I'd use J instead of c.

what does IMHO mean?
