Javascript: Print Object attribute type

Question

I have code something like below

var obj = {
  11 : "November", 
  };

for ( var prop in obj ) {
  console.debug(typeof prop) ;
};

As I am curious, I tried getting typeof attribute in a object, but javascript is returning typeof its value. In Other words I need typeof key but I am getting typeof value.

Is there any way ?

Thank you.

Object keys will always be strings .. Hope this helps https://stackoverflow.com/a/3633390/7785337 — Maniraj Murugan, Dec 21 '19 at 06:32

Please try this one, I think it's helpful for you.

keys = Object.keys(obj);
for(key of keys) {
    console.log(typeof key);
}

You can refer to the following documentation.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in

The for...in loop iterates over the properties of an object, if you want to access the value, just console.log(obj[key])

Try the code below.

var obj = {
  11: "November",
  l2: "December"
};

for(const key in obj) {
  console.log(key)
  console.log(obj[key])
}
// 11
// November
// l2
// December
