Get the value from an object when you don't know the keys

Question

I am passed an object lets say called myobj.

Key: last, Value: "Yellow"

To get the key it is

Object.keys(myobj) // = ["last"]

To get the value it is

myobj.last // = "Yellow"

But I want to handle any key. So in pseudo code I want to combine these.

myobj.Object.keys(myobj)  // to return "Yellow" or whatever the incoming key of the object is.

You can use square bracket notation to access object property

var myobj = {
  last: "yellow"
};

var res = myobj[Object.keys(myobj)[0]];

document.write(res);

This relies on knowing that the key is at zero index. For a more complex object with several properties how do you do it? – JohnnyBizzle May 22 '16 at 13:08

Use for loop and iterate over the key array ( or use forEach iterator ) and get property based on key – Pranav C Balan May 22 '16 at 13:10
