Welcome to the forum!
What issues do you have with this task?

Adam There is a Problem with the challenge I think.
Check this:

  • checkObj({gift: "pony", pet: "kitten", bed: "sleigh"}, "gift") should return the string pony.

  • Passed:checkObj({gift: "pony", pet: "kitten", bed: "sleigh"}, "pet") should return the string kitten.

  • Passed:checkObj({gift: "pony", pet: "kitten", bed: "sleigh"}, "house") should return the string Not Found.

  • Passed:checkObj({city: "Seattle"}, "city") should return the string Seattle.

  • Passed:checkObj({city: "Seattle"}, "district") should return the string Not Found.

  • Failed:checkObj({pet: "kitten", bed: "sleigh"}, "gift") should return the string Not Found.

on the very first pass you see “gift” should return “pony”.
and on the last failed why do I see “gift” should return Not Found

#4

Different objects are passed into the function on different tests.

#5

Would you mind can you please provide me the solution.

#6

We aren’t allowed to write solutions for users.

You need to use the obj passed into the function.

#7

See Than:

function checkObj(obj, checkProp) {
// Only change code below this line
  obj = {
    gift: "pony",
    pet: "kitten",
    bed: "sleigh",
    city: "Seattle"
};

if(obj.hasOwnProperty(checkProp)) {
  return obj[checkProp];
} else {
  return "Not Found";
}
// Only change code above this line
}
#8

You need to delete this

#9

if I delete this how does the code works without object items

#10

The object is a function argument

#11

than once we initialize it. its Automatically became Global
and if I need to delete this how can I pass all without initializing it inside the function either In the comments

#12

You don’t put the object anywhere. The values of the arguments are determined when the function is called.

This says obj = {pet: "kitten", bed: "sleigh"} and checkProp = "gift" for the function call.

#13
  1. checkObj({gift: "pony", pet: "kitten", bed: "sleigh"}, "gift") should return the string pony .
  2. checkObj({pet: "kitten", bed: "sleigh"}, "gift") should return the string Not Found .
    both contains the same obj items
#14

And

The objects look different to me

#15

Still Stuck I think I should work hard to understand this.

#16

Did you try deleting the part I said to delete?

#17

yup and now I see blank

#18

function checkObj(obj, checkProp) {
// Only change code below this line
obj = {

};

if(obj.hasOwnProperty(checkProp)) {
return obj[checkProp];
} else {
return “Not Found”;
}
// Only change code above this line
}

#19

Delete all of this! The whole thing.

#20

You mean like this:

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

}
