JS basics help :(

Tell us what’s happening:
i do as asked but the editor says " You should not modify the myDog setup", which i did not, all i did is put a very simple line of code as asked

Your code so far

// Setup
var myDog = {
"name": "Happy Coder",
"legs": 4,
"tails": 1,
"friends": ["freeCodeCamp Campers"],
"bark": "woof"

// Only change code below this line
delete myDog.tails;
