Use the delete Keyword to Remove Object Properties question!

JavaScript
1

Tell us what’s happening:
it seems that I’m missing something in the syntax, i was trying to delete more than one key in one line and it seems that it is not working for some reason, my question is : is it wrong to do it this way?

Your code so far


let foods = {
  apples: 25,
  oranges: 32,
  plums: 28,
  bananas: 13,
  grapes: 35,
  strawberries: 27
};

// change code below this line
delete foods['oranges','plums','strawberries']
// change code above this line

console.log(foods);

To do it in one line you need:

['oranges','plums','strawberries'].forEach(key => delete foods[key]);

this is new! so basically you are using all the keys as one object? so if i want to delete more than one i have to put them in an array. this is amazing. thank you!
