Why does the below dot notation returns undefined and the bracket notation returns correct value?

Tell us what’s happening:

Your code so far

function checkObj(obj, checkProp) {
if (obj.hasOwnProperty(checkProp)) {
  return  obj.checkProp;
} else

// Only change code below this line
return "Not Found";
// Only change code above this line
checkObj({gift: "pony", pet: "kitten", bed: "sleigh"}, "gift")

Challenge: Testing Objects for Properties

Link to the challenge:

this will return a value only if the object has a property that is literally named checkProp, dot notation can’t be used with variables
