  content: 'Anything you can do, Chuck Norris does better.'
}

// Task 1
// Using `for..in`, `console.log` all property names of the `joke` object,
// concatenating string `joke.` first. 
// Expected result : 'joke.category', `joke.url`, `joke.content`

for (var key in joke) {
    console.log(`joke.${key}`)
}


// Task 2
// Using `Object.keys` get the array of property names (keys) from the object joke 
// and `console.log` that array.
var propertyNames = Object.keys(joke);

console.log(propertyNames);


// Task 3
// Using keyword `delete`, remove the property `url` from the object joke.

delete joke.url;
console.log(joke);


// Task 4 
// Using dot notation add method (function) `hint` to the joke object.
// Method should `console.log`: "The joke is stored in the property .content"

joke.hint = function() {
  console.log("The joke is stored in the property .content")
}
