so I’m not sure what I’m doing wrong.

Your code so far

function checkObj(obj, checkProp) {
  // Only change code below this line
  if (obj.hasOwnProperty(checkProp)) {
    return obj[checkProp];
  } else {
  return "Not Found";
  // Only change code above this line
}

Which tests are failing?

3

checkObj({gift: "pony", pet: "kitten", bed: "sleigh"}, "gift") should return the string pony .
is what i’m failing but im confused because it doesn’t ask me to input an object and when I do i get the same test wrong.

4

I ran your code, The only thing missing is a closing curly bracket “}” at the end.

5

You should see a syntax error in the output. Do you not?

Your code so far

    gift: "pony",
    pet: "kitten",
    bed: "sleigh",
    city: "Seattle"
  };

  // Only change code below this line
var answer = "Not Found";

Please remove the top part where you declare myObj. Also remove the bottom part checkObj(“gift”). You need to change code only in between the lines suggested.

Also the function’s parameter is ‘obj’. But in your code you are working on ‘myObj’. So you are not referring to the same object here. Pls fix the names. Thats it!

8

The argument for checkObj function here is obj not myObj.

  function checkObj(obj, checkProp) {

  // Only change code below this line
    var Obj = {
    gift: "pony",
    pet: "kitten",

    city: "Seattle",
  };
var answer = "Not Found";

  if (Obj.hasOwnProperty(checkProp)) {
    answer= Obj[checkProp];
  }

Hi,
in the if clause you are not checking the right parameter.(is your argument obj or Obj? :upside_down_face:. Case matters in variables.
