Sometimes we have required entries and want to combine them with others. Below, we need to make a list of gifts for the class. We must give the teacher an apple, but the rest is up to us.

Try It

const requiredGifts = {
  teacher: 'apple',
}

const makeGiftList = assignOverrides(requiredGifts)

const giftList = makeGiftList({
  teacher: 'coal',
  sam: 'pokemon card',
  jen: 'phone case',
})

console.log(giftList)
// is {
//   teacher: 'apple',
//   sam: 'pokemon card',
//   jen: 'phone case'
// }
const requiredGifts = {
  teacher: 'apple',
}

const makeGiftList = assignOverrides(requiredGifts)

const giftList = makeGiftList({
  teacher: 'coal',
  sam: 'pokemon card',
  jen: 'phone case',
})

console.log(giftList)
// is {
//   teacher: 'apple',
//   sam: 'pokemon card',
//   jen: 'phone case'
// }

Try It

const requiredGifts = {
  teacher: 'apple',
}

const makeGiftList = assignOverrides(
  requiredGifts
)

const giftList = makeGiftList({
  teacher: 'coal',
  sam: 'pokemon card',
  jen: 'phone case',
})

console.log(giftList)
// is {
//   teacher: 'apple',
//   sam: 'pokemon card',
//   jen: 'phone case'
// }
const requiredGifts = {
  teacher: 'apple',
}

const makeGiftList = assignOverrides(
  requiredGifts
)

const giftList = makeGiftList({
  teacher: 'coal',
  sam: 'pokemon card',
  jen: 'phone case',
})

console.log(giftList)
// is {
//   teacher: 'apple',
//   sam: 'pokemon card',
//   jen: 'phone case'
// }
