Function checkObj modify

JavaScript
#1

Tell us what’s happening:
Describe your issue in detail here.
Modify the function checkObj to test if an object passed to the function ( obj contains a specific property ( checkProp ). If the property is found, return that property’s value. If not, return “Not Found” .

  **Your code so far**


function checkObj(obj, checkProp) {
// Only change code below this line
if (checkObj.hasOwnProperty(checkProp)) {
  return checkObj[checkProp];
}

return "Not Found";
// Only change code above this line
}

Repeating the challenge description is not helpful. What are you having trouble with?

You’re calling hasOwnProperty on the function?

#3

checkObj is not the name of the function parameter.

I’m calling with a if to check the condition, I think that this is the way

#5

You are calling it here, but

checkObj is the name of the function. You can’t call hasOwnProperty on the function. You need to call hasOwnProperty on a variable.

#6

Do you mean the variable name of the object being checked?

If yes, I cant find it. In the example is “myObj”, but there is no object declared in the code

#7

There are only two variables that exist as far as your function knows, obj and checkProp.

Well I tested both variables after you said and it still didn’t work.

function checkObj(obj, checkProp) {
// Only change code below this line
if (checkProp.hasOwnProperty(checkProp)) {
  return checkObj[checkProp];
}

return "Not Found";
// Only change code above this line
}

function checkObj(obj, checkProp) {
// Only change code below this line
if (obj.hasOwnProperty(checkProp)) {
  return checkObj[checkProp];
}

return "Not Found";
// Only change code above this line
}

That’s because you still didn’t fix this line… checkObj is the function. obj is the object that is passed into the checkObj function.

Both of those code snippets use checkObj, which is not the name of a variable. It is the name of the function.
