Answer 1

const json = `{ "N0909": {
"Starter Package": 12,
"Stone": 2942,
"Spruce Log": 0,
"Oak Log": 932,
"Iron": 0 }
}`;

var obj = JSON.parse(json).N0909; // get the object

var output = [];

for(var key in obj) {
if(obj[key]>0) output.push(key)
}

console.log(output.join(',')) // output is keys with value>0 (in array)
