Basic JavaScript - Testing Objects for Properties

Tell us what’s happening:
Describe your issue in detail here.

if i have a property in an object and i can call on that property by simply doing the following for example.

let Dogcharacter= {
“Springer”: “Lively”;
“Terrier”: “Fiesty”;
“Bull dog”: “Lazy”:

if i want to call on Terrier character i would do return Dogcharacter.Springer. For this example i used return obj.checkProp to return the specific property but it kept failing, i then used return obj[checkProp] and it worked perfectly. Why didnt it work the obj.checkProp given that the .function and work the same?

Your code so far

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

When you’re trying to access an object using a variable (i.e. checkProp), you cannot use dot notation, only bracket notation.
