Basic Data Structures - Use the delete Keyword to Remove Object Properties

JavaScript
1

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

I have more of a question about this.

So the exercise has us deleting values in an object using delete foods.value;

So my question is this. Rather than continuously writing the delete keyword along with the expression, is it possible to just write it once using an array for the values?

Something like this…

delete foods.[value1, value2 etc…]???

Your code so far

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

// Only change code below this line

// Only change code above this line

console.log(foods);

You cant just do delete foods[all the things i want to delete], but you could make an array with all the keys and loop over that array and use it to delete everything in that array like this:

let myArr = ['oranges', 'plums', 'strawberries'];

for(let i = 0; i < myArr.length; i++) {

delete foods[myArr[i]];

}

Thank you very much for the reply. I see exactly what you did there and it makes sense. I was just wondering if JavaScript had some kinda shorter syntax to delete keys and values. Thank you again for your hasty reply.
