you don’t loop an object with for each.

probably that can help: https://stackoverflow.com/questions/921789/how-to-loop-through-a-plain-javascript-object-with-the-objects-as-members

You can’t loop on an object. But you can loop over object.keys().

must declare properly the object

e.g

let kursiss = [{ key: 9C , value: ""},{ key: 9D, value: ""}];

for(let _obj of kursiss)
{
 console.log("value ->",_obj.key);
}
