Tell us what’s happening:
Describe your issue in detail here.

Your code so far

function checkObj(obj, checkProp) {
  // Only change code below this line
 var checkObj = ({gift: "pony", pet: "kitten", bed: "sleigh"}, "gift") 
   return "pony",
 var checkObj = ({gift: "pony", pet: "kitten", bed: "sleigh"}, "pet")
    return "kitten",
 var checkObj = ({gift: "pony", pet: "kitten", bed: "sleigh"}, "house")
    return "Not Found";
 var checkObj = ({city: "Seattle"}, "city")
    return "Seattle";
 var checkObj = ({city: "Seattle"}, "district")
    return "Not Found";
 var checkObj = ({gift: "pony", pet: "kitten", bed: "sleigh"}, "gift")
    return "Not Found";
}
  // Only change code above this line

Challenge: Basic JavaScript - Testing Objects for Properties

Link to the challenge:

I am completely lost. I was able to have the first variable to return ‘pony’. And I’m sure I have this all wrong after that. Can you point me towards a few steps that would help me figure this out?

step 1 is going to have to be to reset this exercise back to its initial state as what you are doing is not correct and cannot be fixed.

I would suggest starting by looking at the example and the text of the step to understand the lesson itself first.

for eg.

const myObj = {
  top: "hat",
  bottom: "pants"
};

myObj.hasOwnProperty("top");
myObj.hasOwnProperty("middle");

in the given example, what were they trying to teach us?

Let me know what you think (please give a detailed answer) and we can go from there.

After looking closer, this is what I have.

  var checkObj = ({ 
    gift: "pony", 
    pet: "kitten",
    bed: "sleigh"
    });
  var checkObj = ({
    city: "Seattle"
  });
    
  checkObj.hasOwnProperty("gift");
  checkObj.hasOwnProperty("house")
  return "Not Found";

I still cant seem to find a way to return Gift, Pet, and City to their corresponding values.

please reset again.
Here’s the original code

function checkObj(obj, checkProp) {
  // Only change code below this line
  return "Change Me!";
  // Only change code above this line
}

You need to add code between the two comment lines without changing anything else.

You do not need to define an object

you are -given- an object in the parameter list for checkObj function

you also do not need to hardcode any property. You are given that property in the parameter list as well.

5

Ok, In this example. Is the obj = top:?
And is the property = “hat”?

Or should I be using something different like an if/else statement?

6

in the example the object is the const myObj variable

and hasOwnProperty is being used to check if a specific property exists in that object or not.

7

Ohhhh

if (myobj.hasOwnProp(checkProp)){
   return myobjective[checkProp];
}
else {
  return "Not Found";
}

because the parameter list is called above?

I changed some details to hide the answer.

8

the parameters are what the functions gets, yes.

(you call the function and pass it what it needs)

9

Got it now. That was a biggie. Do you possibly have a better to remember that? Or should I just do it over and over until it sticks?

10

to remember ? (not sure what it is you are trying to remember?)

11

Lol, My apologies. I understand it. Thanks.
