javascript Object.keys and Object.values both return a sequence number instead of the actual key or value

Question

Anyone have had an issue before where running javacript Object.keys or Object.values returns a sequence number as string instead of the actual key or value? In otherwords, if I have three properties in my object and I run e.g:

for(var value in Object.values(myObject)){
 console.log(value);
}

It prints out:

0
1
2

Any ideas why this might be happening? It is a JSON object, so the value is not just string, but nested, if that makes any difference.

A for ... in loop loops through the keys of an object, and Object.values() returns an array. — Pointy

Object.values(myObject) returns an array, and value is the index in a for .. in. use for ... of to get the value instead. — Get Off My Lawn

You should go for for ... of loop to log out the actual values of your object. — vrintle

You'll want to do this instead:

for (const value of Object.values(myObject)) {
  console.log(value);
}

in is for iterating through the property keys of an object, of for the values of an enumerable (like arrays). var value in Object.values() is numbers because those are the keys of the Object.values(...) array.
