Testing Objects for Properties 1

Tell us what’s happening:

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];
 }
  return "Not Found";
}

// Test your code by modifying these values
checkObj("gift");

If I understand your question, the statement myObj.checkProp would give an error because checkProp is not the name of a property. It is a variable containing a string. How do you access a property with variable for the property name? myObj[checkProp]

The eqivalence, if you want it, is that

myObj.gift

and

myObj["gift"]

would be the same thing. But if the property is stored in a variable, you must use brackets.
