Tell us what’s happening:
the code should run as i think i completed the requirements…but still its not working

Your code so far



//setup
var myObj={
gift : "pony",
pet : "kitten",
bed: "sleigh",
};
function checkObj(checkProp){
//your code here
if (myObj.hasOwnProperty(checkProp)){
return myObj[checkProp];
}
else{
return "Not Found";
}
}
console.log(checkObj("gift"));

The function checkObj() takes 2 parameters (obj, checkProp), but you are only passing one.

You don’t need to define the object yourself, it is passed as a parameter.

function checkObj(obj, checkProp) {
  if(obj.hasOwnProperty(checkProp)){
    return obj[checkProp];
  }
  return "Not Found";
}

You don’t have to write the else block as the second return will only run if the if block equates to false.

Also as Gilbert said you need to have the obj as a parameter.

You can do this in just a single line with the es6 syntax,

const checkObj = (obj,checkProp) => obj.hasOwnProperty(checkProp) ? obj[checkProp] : "Not Found";

This obviouly comes at the expense of readability, but the overall code becomes less.
