Distinct values confusion

Question

Why is the code not seeing the additional items?

function main() {

let products = new Set([
"dumbbells",
"barbell",
"t-shirt",
"swim short",
"gloves",
"training apparatus",
"goggle",

]);

var count = 0;
while(count<3, count++){
var itemType = readLine();
//add the item to the set
products.add(itemType);
}

//calculate and output the count of item types
for (let count of set.products())
console.log(products.size);
}

Answer 1

The while-loop is mistakenly constructed.

while( count < 3 )
{
// code here
count++;
}

Or alternatively,

while( count++ < 3 )
{
// code here
}

I'm not sure what you're trying to do with the for-each loop at the bottom. As I understand it, `Set` stores unique data, so every `Set` entry should be unique (no duplicates).

I don't think it is a good idea to use a `Set` for counting frequency of data.

Thank Ipang!
I tried the first loop from the previous example as a shot in the dark.
