将值推送到数组的 object

Question

So I have an array of objects called products:

const  products = [
   {
    name: 'Pants'
   },
   {
    name: 'Shoes'
   },
   {
    name: 't shirts'
    }
 ]

And the list contains a lot more products with other values apart from name. So suppose i forgot to give each product, (object) a coupon's array, it would take me quite a while to update each object manually.

Is there a function that I can create which will push a coupons value into each object as an array? So the final array would look like:

 const  updatedProducts = [
   {
    name: 'Pants',
    coupons: []
   },
   {
    name: 'Shoes',
    coupons: []
   },
   {
    name: 't shirts',
    coupons: []
    }
  ]

Answer 1

const updatedProducts = products.map(product => ({ ...product, coupons: [] }))

Answer 2

Yes you can add properties in javascript like this: products.forEach(product => product.coupons = []);
